Many actors move to the United States hoping to succeed in the highly competitive film industry. To broaden their opportunities and appeal to American casting directors, they often learn to speak with a standard American accent. After living and working in California for a long time, their original accents can disappear completely. This results in a curious change, where these celebrities eventually sound just like people born and raised in the United States when they appear in public.
Christian Bale
As a movie fan, I’ve always been fascinated by Christian Bale’s dedication. He’s a Welsh-born actor who spent his childhood moving around England before making it big in America. What really sets him apart is how completely he transforms for a role – he doesn’t just play a character, he becomes them, right down to mastering an accent for the entire shoot. It’s actually pretty remarkable. You might not realize it now, but his original British accent has faded quite a bit over the years, simply from living in the US for so long. If you stumble across some of his older work, you’ll be surprised at how distinctly British he sounds – it’s a far cry from the American voice we’re used to hearing now!
Charlize Theron
Charlize Theron was raised on a farm in South Africa and grew up speaking Afrikaans. She didn’t become fully fluent in English until she moved to the United States as a young woman to become a model and actress. As she lived in America and took on various film roles, she lost her South African accent, and now speaks with a flawless American accent, giving no indication of where she came from.
Portia de Rossi
Portia de Rossi is an Australian actress best known for her roles in ‘Ally McBeal’ and ‘Arrested Development’. Early in her career, she deliberately worked with a vocal coach to lose her Australian accent, hoping to avoid being limited to certain types of roles in Hollywood. This training worked so well that she now speaks with an American accent all the time. Because of this, many people don’t realize she was born and raised in Victoria, Australia, as her original accent is no longer noticeable.
Gary Oldman
Gary Oldman is a highly respected British actor celebrated for his ability to convincingly portray a wide range of characters, largely due to his remarkable voice. Interestingly, after living in the US for many years, he found he’d lost his native English accent. He even had to work with a vocal coach to regain it for his part in ‘Tinker Tailor Soldier Spy,’ demonstrating how much an actor’s speech can be shaped by where they live long-term.
Anthony LaPaglia
I’ve always been a huge fan of Anthony LaPaglia, and it’s amazing to me how dedicated he was to his craft! He’s actually Australian, but he moved to the US in the early 80s hoping to make it on stage and in movies. He quickly found out his Australian accent wasn’t really working for most American roles, so he spent years mastering a New York accent. It’s so convincing that a lot of people, myself included, were totally surprised to learn he wasn’t originally from the States! You honestly hardly ever hear his natural accent anymore – he really committed to the role!
Simon Baker
Simon Baker became well-known around the world for his role in ‘The Mentalist,’ where he played a consultant and used a typical American accent. Though he’s originally from Tasmania, Australia, and started his acting career there, he adopted the American accent when he moved to Hollywood. Over the years, his natural Australian pronunciation has changed, becoming more neutral and sounding more American. Now, he generally uses this modified voice when giving interviews or appearing in public in the United States.
Yvonne Strahovski
Yvonne Strahovski is an Australian actress who quickly found success in the American TV series ‘Chuck’ after moving to Los Angeles. To play her roles, including in ‘The Handmaid’s Tale,’ she perfected an American accent, and over time, this has become her dominant way of speaking. Though she hasn’t lost her Australian accent completely, she now sounds very American in most interviews.
Rose McGowan
Rose McGowan was born in Italy and spent her childhood moving around Europe. When she was a teenager, her family moved to the United States, and while she initially spoke with a European accent, she quickly learned to speak like a native American. By the time she became famous on ‘Charmed,’ her accent was completely American, and she’s continued to speak that way throughout her career.
Mila Kunis
You know, it’s fascinating to me how Mila Kunis picked up English. She and her family left Ukraine when she was just seven, and she didn’t know a word of English then! She basically taught herself by watching TV and hanging out with kids in LA. It’s amazing because she started so young and worked steadily in American films that her original Russian accent completely faded. Now, she’s got this really recognizable California vibe to her voice – you can definitely hear it in movies like ‘Black Swan’, and it’s just become part of who she is.
Isla Fisher
Isla Fisher started her acting career on the Australian TV show ‘Home and Away’ and later moved to Hollywood. After living abroad for many years, she’s noticed her accent has become a mix of Australian and American. Although she can still speak with her original Australian accent, she often finds herself naturally speaking with an American tone in everyday life. This change in her voice has made it easier for her to play many different comedic roles in American movies.
Naomi Watts
Naomi Watts was born in England, then moved to Australia as a child, and eventually made her home in the United States. Over time, her accent has become a blend of American and transatlantic influences, sounding primarily American. Because she frequently portrays American characters and has lived in New York and Los Angeles for much of her adult life, she’s largely lost the accent of her British and Australian upbringing.
Andrew Garfield
Andrew Garfield was born in the US, but he moved to England as a baby and grew up in a British home. Though he has both American and British citizenship, he developed a distinct English accent that he used when he first started acting. After becoming famous in films like ‘The Amazing Spider-Man,’ his voice began to sound more generally American. He’s now so skilled at switching between accents that it’s hard to know what his natural voice really is.
Pierce Brosnan
Born in Ireland, Pierce Brosnan moved to London as a child and later became famous worldwide in the United States. Over time, his Irish accent softened and evolved while playing James Bond, becoming more refined and international. After living in Malibu for many years, his voice now has a noticeable American sound, though hints of his Irish roots can still be detected. Most of the time, however, he speaks with an American accent.
Alex O’Loughlin
Alex O’Loughlin, an Australian actor, is best known for his role on the American TV show ‘Hawaii Five-0’, where he played Steve McGarrett for over ten years. To convincingly portray the character, he used an American accent for most of the year. This consistent effort actually changed the way he speaks naturally. Now, even when he’s not acting, he often speaks with a noticeable American tone, sometimes overshadowing his Australian roots.
Poppy Montgomery
Poppy Montgomery moved from Australia to Los Angeles as a teenager to become an actress, and she had very little money when she first arrived. She worked tirelessly to lose her Australian accent so she could land roles in American TV shows like ‘Without a Trace’. She became so good at it that she now sounds like a native American in most situations. Interestingly, she’s said her children are surprised when she attempts to speak with her original Australian accent.
Ryan Kwanten
Ryan Kwanten, an Australian actor, gained popularity in the US playing Jason Stackhouse on ‘True Blood’. He worked hard to develop a Southern American accent for the show, and it ended up changing the way he speaks naturally. Even after the series finished, his voice retained a noticeable American influence, a far cry from how he sounded growing up in Sydney. Kwanten is a great illustration of how an actor’s work can permanently affect their speech patterns.
Jason Clarke
Jason Clarke is an Australian actor who’s been in many popular American movies, including ‘Zero Dark Thirty’. After living and working in the US for a long time, his Australian accent has become very faint. He frequently plays tough American characters and has completely adopted the way they speak. As a result, many people are surprised to hear him now speaking with a consistent, neutral American accent in interviews.
Joel Edgerton
Joel Edgerton has become a successful actor in Hollywood by taking on diverse roles. Though he’s originally from New South Wales, Australia, years of working in American films have subtly changed his accent. He often finds himself speaking with an American tone even when he’s not filming, making him a popular choice for American dramas and thrillers.
Jai Courtney
Jai Courtney, an Australian actor, became known for appearing in big American action movies like ‘A Good Day to Die Hard’. Because he’s spent so much of his career performing in American or neutral accents, his natural speaking voice has changed. Now, when he does interviews and public appearances, he speaks with a distinctly American sound, a result of his time working in Hollywood.
Sam Worthington
Sam Worthington became famous worldwide with his role in ‘Avatar’ and has spent many years living in the United States. While originally from England and raised in Australia, his voice now sounds distinctly American. He sometimes finds it difficult to use a consistent Australian accent when speaking in interviews, as he’s become accustomed to the way his characters speak. This change is due to his long career in the American film industry and the fact that he spends most of his time with people in Los Angeles.
Abbie Cornish
Abbie Cornish is an Australian actress who moved to the US to pursue bigger roles in film. After years of playing characters who required an American accent, her speech has become more Americanized. Many people who aren’t familiar with her earlier work now think she’s a native American actress.
Teresa Palmer
Teresa Palmer relocated from South Australia to Los Angeles to pursue a film career, including roles in movies like ‘Warm Bodies’. She’s discussed the work she put into modifying her Australian accent to advance her career. Over time, her natural Australian voice has become softer and taken on American vowel sounds. Now, she generally speaks with a noticeable American accent in interviews and on screen.
Rose Byrne
Rose Byrne is an Australian actress who’s become well-known for starring in popular American comedies after building her career with dramatic roles. Living and working in New York for many years, surrounded by American accents, has subtly changed the way she speaks. While she can still do an Australian accent, her everyday speech now often sounds more American.
Katherine Langford
I have to admit, I was genuinely surprised to learn Katherine Langford isn’t American! She really nailed the US high school student role in ’13 Reasons Why,’ and her accent was so spot-on, it fooled a lot of us. It seems like she’s been consistently working on American projects ever since, and honestly, it’s really softened her Australian accent. If you’re just discovering her now, you might not even realize she’s originally from Perth – it’s become much more subtle over time.
Dacre Montgomery
Dacre Montgomery became widely known for playing Billy Hargrove on the American show ‘Stranger Things’. He fully embraced the character, even adopting the way teenagers spoke in the 1980s. This dedication had a surprising effect – his natural voice now has a noticeable American accent. Even when he’s not acting, he tends to speak with the same rhythms and inflections he uses for his role.
KJ Apa
KJ Apa, a New Zealand actor, rose to fame playing Archie Andrews in ‘Riverdale’. For almost ten years, he’s spent months each year perfecting an American accent for the show. As a result, his natural New Zealand accent has faded, and he often sounds more American than Kiwi when he’s just talking casually.
Sarah Snook
Sarah Snook, an Australian actress, became widely known for her role as Siobhan Roy in the American series ‘Succession’. Her portrayal was so convincing that many viewers believed she was American herself. After years of playing a wealthy American character, her voice has subtly changed, now carrying an American accent as a result of the extensive vocal training she did for the part.
Toni Collette
Toni Collette is known as one of Hollywood’s most adaptable actresses, largely because of her ability to convincingly perform with different accents.

She often uses a more neutral or American accent instead, which showcases both her talent and how much her work environment has influenced her speech.
Margot Robbie
Margot Robbie started her career on Australian television before becoming a major star in American movies. She’s known for playing diverse American roles, from characters originating in places like Brooklyn to the Pacific Northwest. Because of this, her natural Australian accent has changed considerably and now sounds more international.

Hugh Jackman
Hugh Jackman is a globally recognized Australian actor who has worked for many years in the United States on large film series. While he originally had a strong Australian accent, it has become more subtle and American-sounding over time. He often uses a standard American accent when acting in movies and performing on stage, and living and working in the US for so long has significantly shaped the way he speaks.
Nicole Kidman
Nicole Kidman was born in Hawaii to Australian parents, but she grew up in Sydney, Australia. She moved to Hollywood in the late 1980s and has become a major star in American films.

Guy Pearce
Guy Pearce is a successful Australian actor who has worked in Hollywood while living in different countries.

Eric Bana
Eric Bana started his career as a comedian in Australia, but later moved into dramatic acting in the US. He’s spent considerable time living and working in America on films like ‘Hulk’ and ‘Munich’.

Jane Seymour
Jane Seymour is a British actress best known for her role in the American TV series ‘Dr. Quinn, Medicine Woman’. She’s lived in California for many years and has become accustomed to the American way of life. Over time, her English accent has softened and become more American-sounding, leading many US viewers to see her as a familiar, local celebrity because her voice is so common in American media.
Mischa Barton
Mischa Barton was born in London, but her family moved to New York when she was young so she could pursue a career in acting and modeling.

She’s spent almost her whole life and career working in American entertainment, so she still speaks with an American accent.
John Barrowman

Kim Cattrall was born in England but moved to Canada as a baby and later to the United States.

Dominic Purcell
Dominic Purcell is an Australian actor originally born in England who became well-known for his role in the American TV show ‘Prison Break’.

Callan Mulvey

Elizabeth Debicki
I’m a big fan of Elizabeth Debicki! She’s an Australian actress who’s really made a name for herself in both American and British films. It’s amazing how she’s worked all over the world, and she’s so good at doing different accents for her roles. Because she’s moved around so much for work, her Australian accent has actually softened over time. Now, she speaks with this really polished, almost neutral voice – it’s so subtle that it’s hard to even tell where she’s originally from just by listening to her. It really adds to her versatility as an actress!
