It’s common in Hollywood for actors well into adulthood to play teenagers or characters much younger than themselves. This often requires viewers to overlook the obvious age difference. Casting choices usually focus more on an actor’s talent and popularity than on how closely they match the character’s age, leading to performances where the actor appears older than the role calls for.
Ben Platt

Despite being close to thirty years old, he starred as the teenage lead in the movie version of ‘Dear Evan Hansen’. Many viewers criticized the attempts to make him look younger with makeup and lighting. While he successfully captured the character’s voice, his noticeably older appearance was a distraction. Reviewers pointed out that his mature look didn’t fit the high school environment of the story.
John Travolta

John Travolta famously played a high school student, Danny Zuko, in ‘Grease’ even though he was in his mid-twenties at the time. He brought a lot of charm and great dancing to the role, but clearly looked older than a typical teenager. The rest of the main cast was also significantly older than the high school characters they portrayed. This practice of casting older actors as teens has become a well-known example in Hollywood.
Andrew Garfield

Sony chose Garfield to play Peter Parker in ‘The Amazing Spider-Man’ when he was almost thirty years old. Despite looking older for the role, he brilliantly portrayed the character’s awkwardness and humor. The movie tries to make his age believable by emphasizing his energetic personality and lean physique. Even with the noticeable age difference, his performance is still one of the film’s strongest points.
Tobey Maguire

Tobey Maguire was 27 years old when he first played Spider-Man, a high school student, in the movie. Despite not looking like a teenager himself, he became well-known for his performance as Peter Parker. He perfectly captured the character’s vulnerability and innocence, which were key to telling the story of Spider-Man’s beginnings. Most fans didn’t mind his age because he brought so much emotion to the role.
Alan Ruck

Let me tell you, Alan Ruck absolutely nailed Cameron Frye in ‘Ferris Bueller’s Day Off.’ It’s wild to learn he was nearly thirty playing a teenager! He totally convinced me, though – his youthful looks and the way he portrayed Cameron’s anxiety made it believable. Honestly, it’s one of the most iconic teen performances of the ’80s, and it’s what really gives the movie its heart. Beyond the fun and games, Cameron’s journey is what makes ‘Ferris Bueller’ so special.
Judd Nelson

When Nelson was twenty-five, he played the role of John Bender, the rebellious teen, in ‘The Breakfast Club’. His powerful and realistic performance became the standard for how high school bad boys were portrayed for years to come. He appeared much older and more hardened than most high school students, and this maturity allowed him to seem like the most dominant character during detention.
Ralph Macchio

Ralph Macchio reprised his role as the teenage Daniel LaRusso in ‘The Karate Kid Part III’ around the age of twenty-seven. The story required him to still appear as a young student competing in a tournament for those under eighteen. While he still looked youthful, the difference in his age was starting to show. Macchio found it challenging to convincingly portray the character’s naive innocence at that point in his life.
Roger Moore

Roger Moore was fifty-seven years old when he played James Bond in ‘A View to a Kill.’ Many viewers and critics believe this film marked a point where he was no longer convincingly portraying the character, as he needed extensive use of stunt doubles due to his declining physical abilities. Moore himself later acknowledged he felt too old to handle the role’s demanding action and romantic scenes.
Sean Connery

Sean Connery reprised his role as James Bond in ‘Never Say Never Again’ at the age of fifty-three. While the film acknowledged he was getting older, it still featured him in demanding action sequences that felt somewhat unrealistic. Despite looking more tired than in previous films, Connery’s charm remained, and the movie used his age as a way to explain why he was still in the game.
Robert De Niro

In ‘The Irishman,’ the filmmakers used technology to make the actor appear younger as he portrayed Frank Sheeran over many years. Although his face looked youthful in the beginning, his body often moved in a way that revealed his actual age of seventy-six. This was particularly noticeable in a fight scene with a store owner, which showed the limits of the visual effects. Many viewers found the difference between his young-looking face and his less agile movements to be distracting.
Joe Pesci

Joe Pesci returned to acting in ‘The Irishman’ as Russell Bufalino, and the filmmakers used technology to make him appear younger. While the visual effects smoothed his face, they couldn’t completely mask changes in his voice and how he moved. Despite these inconsistencies, Pesci gave a remarkably subtle and unsettling performance, relying on his naturally intimidating aura rather than physical threats to bring the character to life.
Orlando Bloom

Orlando Bloom returned as the elf Legolas in ‘The Hobbit: The Desolation of Smaug’ a decade after the first ‘Lord of the Rings’ trilogy. Even though elves don’t age, Bloom appeared noticeably older and heavier than he did in the original films. This was visually jarring for fans, as his Legolas was supposed to look younger in ‘The Hobbit’, which takes place later in the timeline. CGI couldn’t completely hide the changes, creating a distracting effect.
Roberto Benigni

The Italian actor both directed and starred as Pinocchio in his 2002 film. However, at nearly fifty years old, he was much older than the traditionally young character, and critics heavily criticized the unusual casting. Despite a lively performance, many found it difficult to overlook the strange choice of having a middle-aged man play a boy.
Martin Short

Robert Short played a ten-year-old character named Clifford in the comedy film ‘Clifford’ despite being forty years old at the time. Filmmakers used clever camera angles and props to make him look smaller alongside the other actors. The movie has gained a dedicated, almost obsessive, following because of how unexpectedly silly the casting is. Short fully commits to the role with a wild, energetic performance that highlights just how unusual the idea is.
Kevin Spacey

Kevin Spacey both directed and starred in ‘Beyond the Sea’, playing the role of singer Bobby Darin. He portrayed Darin throughout his entire life, even in scenes depicting the singer as a young man in his twenties. Some critics thought Spacey’s age made it harder to believe the story, as it drew attention away from the film’s biographical focus. Spacey personally insisted on performing all the songs himself, prioritizing capturing the feeling and spirit of Darin over simply imitating his appearance.
Jason Earles

Despite being in his late twenties, Jason Earles convincingly played Jackson Stewart, the teenage brother on ‘Hannah Montana.’ He looked so young that he was able to play high school students for many years. Interestingly, Earles was actually older than the actor who played his father on the show! His great comedic skills and energetic personality helped him fit right in with the younger cast members.
Cory Monteith

Cory Monteith started playing Finn Hudson, a high school student, on ‘Glee’ when he was twenty-seven years old. While he portrayed a charmingly naive quarterback, he obviously appeared much older than the character he was playing. ‘Glee’ was known for casting actors in their twenties as high school students. Despite the age difference, Monteith’s natural leadership skills fit the role perfectly.
Mark Salling

Josh Salling portrayed the rebellious character Puck on ‘Glee’ as he neared his late twenties. Despite playing a sixteen-year-old student, he appeared older due to his thinning hair and athletic physique. Salling brought a tough, mature edge to the ‘bad boy’ role and remained a key figure in the show’s high school storylines for multiple seasons.
Harry Shum Jr.

Harry Shum, the actor who played Mike Chang on ‘Glee’, was around twenty-seven years old when the show began, portraying a high school student. The character initially highlighted Shum’s impressive dancing abilities. While he appeared older than the teenage characters, he blended in well with the rest of the cast. He continued to play a student throughout the series, even as he approached his thirties.
Luke Perry

Luke Perry became a popular teen star in his mid-twenties when he played Dylan McKay on ‘Beverly Hills, 90210’. Despite looking older than a typical high school student due to his mature features and hairline, he perfectly embodied the character of a thoughtful, independent loner. He was able to make the role work thanks to his natural charm and talent as an actor.
Ian Ziering

Ian Ziering became known for playing high school student Steve Sanders on ‘Beverly Hills, 90210,’ starting when he was twenty-six years old. He continued in the role for a decade, eventually portraying Steve as a college student and then an adult. Throughout his time on the show, Ziering’s lively performance often hid the fact that he was much older than the character he played. ‘Beverly Hills, 90210’ is frequently mentioned as a classic example of a nineties show featuring adult actors playing teenagers.
Paul Wesley

Wesley portrayed a teenage vampire on ‘The Vampire Diaries’ despite being in his late twenties. The show explained this by saying his character was magically frozen at that age. However, as the series went on for eight seasons, Wesley naturally aged, making it more and more obvious that a man in his thirties was playing a high schooler.
Ian Somerhalder

Ian Somerhalder played Damon Salvatore, a vampire who was meant to look eternally young. While Somerhalder himself aged throughout the show – starting in his thirties and continuing into his late thirties – his character was supposed to be physically 25 forever. This created a contrast because the actor noticeably aged while playing a character who shouldn’t have.
Tom Welling

Tom Welling began playing the teenage Clark Kent on ‘Smallville’ when he was twenty-four, and continued in the role for a decade. As the series progressed, his character transitioned to a young professional starting out at the Daily Planet. Even when portraying a high school student, Welling appeared physically strong and mature, while his youthful appeal was key to the character’s success in the earlier seasons.
Channing Tatum

In ’21 Jump Street,’ Tatum played a police officer who went undercover as a high school student. A running joke throughout the movie was how obviously older he looked – like a man in his thirties! He played this up for laughs by acting confused about things teenagers would normally know. The humor depended on the audience realizing he was much too old to convincingly play a high schooler.
Leslie Howard

In the 1936 movie version of ‘Romeo and Juliet,’ Howard played the teenage Romeo, even though he was forty-three years old. The film studio chose him because he was a well-known and respected actor, rather than an unproven young performer. While he delivered the beautiful, poetic lines perfectly, his age created an uncomfortable contrast with his much younger co-star and the passionate love story for audiences today.
Humphrey Bogart

Humphrey Bogart starred as Linus Larrabee in ‘Sabrina,’ alongside Audrey Hepburn. At fifty-four, he played a wealthy businessman trying to win the affection of a much younger woman. Many critics pointed out that he appeared more like her father than a romantic interest. Bogart himself was apparently dissatisfied with being cast in the role during filming.
Bing Crosby

At age fifty-three, Bing Crosby played the male lead in ‘High Society,’ competing for the attention of a much younger Grace Kelly. Though a musical remake of ‘The Philadelphia Story,’ the difference in their ages was more noticeable. Even while appearing somewhat weary, Crosby’s singing voice was still perfect.
Gary Busey

Gary Busey was nominated for an Academy Award for his portrayal of a young rock star in ‘The Buddy Holly Story’. Though he was thirty-three years old at the time, and noticeably different in appearance from the actual Buddy Holly, he performed all the songs live on set. This commitment to authenticity, combined with his energetic performance, made up for the physical differences.
Kevin Bacon

Kevin Bacon starred as Ren McCormack, a rebellious teenager, in the movie ‘Footloose’ when he was twenty-five years old. His character moves to a town where dancing is prohibited and enrolls in high school. While he appeared youthful for his age, his noticeably adult physique was hard to ignore. Bacon has often playfully mentioned how difficult it was to fit into his famously tight jeans for the role.
Dustin Hoffman

Dustin Hoffman was thirty years old when he played Benjamin Braddock, a recent college graduate, in ‘The Graduate.’ He brilliantly portrayed the uncertainty and lack of direction many people feel after finishing college. Interestingly, Hoffman was almost the same age as the actress who played the older character, Mrs. Robinson. Despite the unusual age differences among the actors, his performance remains iconic.
Laurence Olivier

Olivier both directed and acted in a film version of ‘Hamlet’, taking on the role of the young prince when he was forty years old. Though he lightened his hair to look younger, his age was still noticeable. His performance was known for its deep, thoughtful exploration of the character’s inner life. He’s still remembered as one of the oldest actors to portray the Danish prince on screen.
Ncuti Gatwa

Ncuti Gatwa, who is almost thirty, convincingly plays a high school student in the Netflix series ‘Sex Education’. He’s energetic and charming, making his character relatable. The show often casts actors much older than the teenage roles they play. Gatwa’s performance benefits from his life experience, adding emotional depth that a younger actor might not be able to achieve.
Charles Melton

Ross Butler, who played Reggie Mantle on ‘Riverdale,’ was almost thirty years old while portraying a high school student. The show frequently cast adult actors as teenagers, likely to better handle its intense and dramatic plots. Butler’s physique made him appear much more developed than a typical high school athlete, but the show’s unique style allowed for this difference in appearance.
Joe Keery

Joe Keery, who plays Steve Harrington on ‘Stranger Things,’ was in his mid-twenties when he first started the show. As the series continued, his character was written as still being in high school. This created a noticeable age difference between Keery and the younger actors he often protected on screen. Despite this, Keery has managed to keep the character feeling believable and endearing.
Henry Winkler

Henry Winkler became famous playing Fonzie, the cool biker, on ‘Happy Days’ when he was twenty-eight years old. His character was written as a high school dropout who spent time with younger teens on the show. Despite being a decade older than the teenage actors, Winkler quickly became the show’s biggest star. His natural charm and appeal made viewers easily accept him in the role, overlooking his actual age.
James Stewart

James Stewart was fifty-three years old when he played a young law student in ‘The Man Who Shot Liberty Valance.’ The film relies on a flashback, and Stewart portrays the younger version of his character with minimal makeup. Instead of trying to make him look young, the filmmakers emphasized his naturally youthful personality and movements. This casting choice is now considered a particularly striking example of how Hollywood used to handle aging actors.
Liam Neeson

In ‘Taken 3’, Liam Neeson played a tough action hero, despite being in his sixties. While he brought a serious tone to the role, the fight scenes needed a lot of quick cuts to mask his reduced speed. The movie had difficulty making his character’s athletic moves seem believable.
Arnold Schwarzenegger

Arnold Schwarzenegger returned to the role of the T-800 in ‘Terminator Genisys’ despite being in his late sixties. The film explained his aged look by stating that the human tissue covering the cyborg naturally ages. However, many fans struggled to accept this older portrayal of the iconic character. The movie used computer-generated imagery to create a fight scene between the older and younger versions of the Terminator.
Brad Pitt

In the early scenes of ‘The Curious Case of Benjamin Button’, Brad Pitt portrayed a younger version of the main character. Although the film centers around aging, Pitt played the teenage years of Benjamin Button using computer-generated imagery. Some reviewers found the effect of digitally placing his head on a younger body to be somewhat unnatural. Pitt was in his forties at the time, while portraying the character at different, younger ages.
Michael Douglas

In the first scene of ‘Ant-Man’, Douglas portrayed a younger Hank Pym. Marvel employed visual effects to make him appear as he did in the 1980s, and while the effect was visually convincing, his voice still sounded mature. The short scene effectively showcased how far digital makeup technology has come.
Samuel L. Jackson

Samuel L. Jackson portrayed a younger version of Nick Fury throughout ‘Captain Marvel’. Using digital technology, filmmakers made him look decades younger to set the story in the 1990s. While he convincingly acted like a younger man, the de-aging process occasionally made his eyes appear unnatural. This film was among the first to feature an actor digitally de-aged for the entire duration.
Harrison Ford

Harrison Ford was in his sixties when he reprised his role as Indiana Jones in ‘The Kingdom of the Crystal Skull.’ While the movie recognized his age, it still featured a scene where his character miraculously survived a nuclear blast inside a refrigerator. A lot of the action sequences were done by stunt doubles or created using visual effects. Many fans thought this Indiana Jones didn’t seem as tough or resilient as he was in the earlier films.
Dave Franco

I always thought James Franco was perfect in ’21 Jump Street’! It was so funny seeing him play a high schooler, especially knowing he was actually twenty-seven. He totally pulled off the ‘cool kid’ vibe, and I think the movie played with that – it was like a wink to the audience about how old actors often play teens. He just looked young enough that it worked for the comedy, you know?
Jonah Hill

In the movie ’21 Jump Street,’ Hill played a police officer who went undercover as a high school student. At twenty-eight years old, he appeared much older than his classmates, and the movie playfully highlighted this. The filmmakers leaned into the humor of his age, and Hill delivered a performance that was intentionally awkward, which added to the comedic effect.
Jesse Eisenberg

Jesse Eisenberg skillfully portrayed a young Mark Zuckerberg in ‘The Social Network,’ even though he was in his late twenties at the time. He convincingly captured the energy of a college student through his fast-paced speaking and body language. Eisenberg looked so youthful that viewers easily believed he was an undergraduate at Harvard. He delivered a performance that made people forget he was almost ten years older than the character he played.
Patrick Stewart

Patrick Stewart played Professor X in ‘X-Men Origins: Wolverine,’ and filmmakers used digital technology to try and make him look much younger for a short appearance. However, the effect didn’t work well and was often compared to a plastic mask. It’s now remembered as one of the first attempts at digital de-aging that didn’t quite succeed.
