20 Actors Who Played Teenagers Well Into Their 30s (and Nailed It)

It’s common in Hollywood to cast adult actors as high school students. This lets filmmakers hire experienced professionals who can easily manage busy filming schedules, avoiding the legal complications of working with child actors. With the help of makeup, costumes, and skillful acting, these performers often convincingly portray teenagers, and audiences rarely notice the difference. In fact, many famous teenage characters have been played by actors well into their 30s or even 40s.

Stockard Channing

Stockard Channing is well-known for her role as the sharp-tongued leader of the Pink Ladies in the 1978 movie musical ‘Grease’. Despite being 33 at the time, she brilliantly portrayed the complex mix of strength and insecurity in her character, high school senior Betty Rizzo. Her rendition of the song ‘There Are Worse Things I Could Do’ is one of the most memorable scenes in the film. Channing convincingly played a teenager alongside other actors who were also older than their characters.

Henry Winkler

Henry Winkler became famous for his role as The Fonz on ‘Happy Days’ – a cool, leather-jacketed high school student. He was 28 when he started the part and continued playing it throughout the show’s ten-year run, even as he got older. His charm and comedic timing made audiences accept that he wasn’t actually a teenager. As Winkler aged, his character evolved into a wise, older figure, mirroring the actor’s own life.

Shirley Henderson

Shirley Henderson played the character of Moaning Myrtle, a ghost, in ‘Harry Potter and the Chamber of Secrets’ when she was 36 years old. Her small size and voice made it easy for her to appear alongside the younger actors. She returned to the role in ‘Harry Potter and the Goblet of Fire,’ nearing age 40. The difference in age between Henderson and the other actors is still considered one of the most unexpected casting choices in the ‘Harry Potter’ films.

Gabrielle Carteris

Gabrielle Carteris started her acting career at age 29, playing Andrea Zuckerman, a smart and dedicated student newspaper editor, on ‘Beverly Hills, 90210.’ While her character navigated the challenges of high school, Carteris herself became pregnant during the show’s later seasons. The producers cleverly used camera work and props to hide her pregnancy and keep the impression that she was still a teenager. Eventually, as the age difference became more noticeable, she decided to leave the series.

Jason Earles

Lucas Earles was known for playing the teenage brother of Hannah Montana on the Disney Channel, even though he was in his late 20s and early 30s at the time. He looked young enough to convincingly play a high school student alongside Miley Cyrus. Earles brought a lot of energetic humor to the role, which matched the show’s silly and playful style. He was 33 years old when the series ended.

Bianca Lawson

In Hollywood, Lawson is known for looking remarkably young, which has allowed her to convincingly play teenage characters for over twenty years. For example, she was 31 when she played a 16-year-old student on ‘Pretty Little Liars,’ and she’s taken on similar roles in shows like ‘Buffy the Vampire Slayer’ and ‘Teen Wolf.’ Audiences generally accept her in these parts because she portrays the emotions of youth so well.

Barbra Streisand

Barbra Streisand both directed and starred in the musical drama ‘Yentl’, playing a young woman who pretends to be a boy. Although she was 41 at the time, critics praised her performance. While the studio worried about her age, her strong singing and acting skills ultimately made the film a success. ‘Yentl’ is notable because Streisand was the first woman to write and direct a major Hollywood movie.

Matt Damon

I was really impressed with Matt Damon in ‘Behind the Candelabra.’ He played Scott Thorson, Liberace’s young lover, and he was 42 at the time, but they made him look like a teenager for the beginning of the movie with amazing makeup and costumes. He didn’t just look young, though – he totally changed his movements and the way he spoke to really capture that youthful innocence. Because the movie covers so many years, it was cool to watch him gradually age the character until he looked closer to his actual age.

Alan Ruck

Alan Ruck is remembered for his unforgettable role as Cameron Frye, the worried best friend in the 1986 film ‘Ferris Bueller’s Day Off’. He was nearing 30 during filming, and his ability to convincingly portray teenage stress and difficult family relationships really connected with viewers, even though he was much older than the character. His strong on-screen connection with Matthew Broderick was central to the film’s emotional impact.

Nicola Coughlan

Nicola Coughlan became well-known internationally for her role as Clare Devlin, a worried and bookish teenager, in the show ‘Derry Girls’. She was 31 when she started filming the comedy, which is set in 1990s Northern Ireland. Coughlan skillfully portrayed the strong feelings and awkwardness of being a teenager, and her performance felt natural alongside the younger actors. She used a higher voice and particular movements to convincingly play a high school student.

Trevor Donovan

Donovan played Teddy Montgomery, a high school tennis star, in the ‘90210’ reboot. At 31, he portrayed a teenager exploring his sexuality, and this storyline became a highlight of the show for its thoughtful and nuanced approach. Donovan’s youthful appearance helped him convincingly play a character much younger than himself – often alongside actors a decade his junior.

Keiko Agena

For seven seasons of the popular show ‘Gilmore Girls’, actress Liza Weil played Paris Geller, Rory Gilmore’s music-loving best friend. She started the show at 27, but portrayed a high school student for years, even into her thirties. Her character kept a secret life, loving rock music despite having a very religious and strict mother. Weil brought a lot of energy and enthusiasm to the role, making it easy to believe she was a teenager trying to become independent.

Harry Shum Jr.

Harry Shum Jr. played Mike Chang on ‘Glee,’ a quiet dancer who gained confidence through the glee club. Despite being 27 when the show started and playing a high schooler for three years, his impressive dance skills were so captivating that viewers didn’t question his age. When his character graduated in season three, Shum Jr. was able to take on more mature roles.

Ashleigh Murray

Madeline Petsch became known for her role as Josie McCoy, the lead singer of the Pussycats, in the TV show ‘Riverdale.’ The show presented a darker take on the classic Archie Comics stories. Petsch was 28 years old when ‘Riverdale’ first aired and continued playing a high school student throughout her twenties and into her thirties, bringing energy and music to the character. Later, she reprised the role for the spin-off series ‘Katy Keene,’ portraying Josie as a young adult.

Antwon Tanner

Tanner became known for his role as Skills Taylor, the friendly basketball player on ‘One Tree Hill,’ starting when he was in his late 20s. He convincingly played a high school student for many years, even into his 30s, until the show advanced the timeline. His humor and how well he fit in with the main group of friends made his age hardly noticeable to the audience. He remained an important part of the show for several seasons as the characters grew up.

Darren Barnet

Darren Barnet became well-known for his role as Paxton Hall-Yoshida, the popular student, in the Netflix series ‘Never Have I Ever’ when he was 29 years old. He skillfully portrayed a character dealing with the challenges of school and relationships while being in his early thirties. To look the part of a teenage swimming star, Barnet stayed in excellent physical shape. His strong connection with the younger actors made the show’s high school environment feel very believable.

Alexa Demie

Alexa Demie won viewers over with her portrayal of Maddy Perez, the stylish and unpredictable cheerleader on HBO’s ‘Euphoria’. Fans were surprised to learn she was around 29 or 30 years old while playing a high school student. Her strong performance and mature presence brought complexity to the character, and she flawlessly captured the look and vibe of today’s Gen Z teens.

Ross Butler

Dylan Butler became known for playing Zach Dempsey, a complex and emotional athlete, in the Netflix series ’13 Reasons Why’. He started the show at age 27 and continued playing the role for several years, even into his 30s. Butler’s portrayal of Zach went against the usual depiction of bullies, revealing a hidden vulnerability. He had previously left another teen series to take on this part, which allowed him to showcase a wider range of emotions.

Joe Keery

Joe Keery quickly became a popular actor for his role as Steve Harrington on ‘Stranger Things’. While Keery was 30 years old during filming, his character was still figuring out life after high school. He brought a funny and likeable quality to Steve, which helped viewers see him in a new light. Plus, his 80s hairstyle and clothes perfectly matched the show’s retro look.

Ncuti Gatwa

Ncuti Gatwa first became famous for his role as Eric Effiong, a lively student, in the series ‘Sex Education’. He started the show at age 26 and played the character for four years, until he was 30. Gatwa’s energy and youthful look made him believable as a high schooler, and he gave a sensitive performance that really captured what it’s like to be a teenager today.
