In a movie famous for its shock twist, perhaps the biggest surprise of all for audiences was discovering that Toni Collette's American accent was not her own. She's from Sydney, Australia, but she sounds so convincing that you'd never guess.
British fans of Helen Fielding's best-selling novel were initially up in arms about the decision to cast an American in the role of Bridget Jones. But Zellweger did her research, going undercover to work in a London office. Her plummy British accent won over the critics.
Australian actress Margot Robbie was widely praised for her convincing Brooklyn accent as Naomi in 'The Wolf of Wall Street.' The thick accent was so good that many people assumed she was a Brooklyn native.
Winslet clearly put a lot of effort into nailing her accent after 'Titanic.' Her American accent in 'Eternal Sunshine of the Spotless Mind' was widely praised, with one BBC reviewer calling it "immaculate."
Welsh-born, English-raised Christian Bale was thoroughly convincing as the titular crazed American in the movie adaptation of the Bret Easton Ellis book. He apparently stuck to the American accent on set at all times, only speaking in his real voice at the wrap party.
Is there anything Idris Elba can't do? The British star acts, directs, and even raps with aplomb, so it's a small wonder that he nailed the accent as South African revolutionary-turned-president Nelson Mandela.

Proving that Brits can do American accents just as poorly as the other way round, acclaimed actor Michael Caine received a mauling for his 'Texan' accent in this flop adventure film.
Anne Hathaway was only marginally more convincing in her role as British writer Emma in the movie adaptation of David Nicholls' novel. Brits rightly questioned just which part of the country her 'northern' accent was supposed to be from.

Johnny Depp has managed some decent accents throughout his career, but this film about London's Jack the Ripper was not his finest moment. Neither he nor co-star Heather Graham convinced with their cartoonish cockney accents.
His character was from Rhodesia or modern-day Zimbabwe, and although DiCaprio scored an Oscar nomination for the role, viewers have had mixed reactions to his accent in the film.
Maybe Caine should take solace from the fact that even American stars can get the Texas accent wrong. Connecticut-born James Van Der Beek was laughed out the park for his accent in this sports-themed movie.
DiCaprio had committed previous crimes against accents. His Irish brogue in 2002's 'Gangs of New York' was widely mocked by audiences, especially in Ireland.
This movie raised questions about the accents across the board, but it was Jolie's attempts at sounding like she came from ancient Greece that were subject to the most withering critiques.

Italian actress and dialect coach Francesca De Martini didn't exactly approve of Lady Gaga's vocal impression of Patrizia Reggiani, who famously hired a hitman to murder her ex-husband, Maurizio Gucci. “I feel bad saying this, but her accent is not exactly an Italian accent, it sounds more Russian,” De Martini told The Daily Beast.
De Martini had initially auditioned to be in the film, and though she was rejected, she was later called back to help Salma Hayek, who herself requested a coach. It was then that she heard Lady Gaga's accent. Gaga herself stirred anticipation around the accent after she told British Vogue that she stayed in character, with both accent and brunette hair, for nine months, but according to the dialect coach, that still wasn't enough. “There are so many different accents,” De Martini noted, adding that Al Pacino’s is more akin to New York-Italian, while Adam Driver barely has any at all.
Marilyn Monroe fans rushed to social media after watching Ana de Armas take on the iconic role in the Netflix film 'Blonde,' with many criticizing the Cuban actress for her accent. Many complained that Armas' accent is too heavy to sound like Monroe, and that it's taking her out of character, but Monroe's estate came to Armas' defense.
“Marilyn Monroe is a singular Hollywood and pop culture icon that transcends generations and history,” Marc Rosen, president of entertainment at Authentic Brands Group, which owns the Marilyn Monroe Estate, said in a statement to Variety, adding that everyone knows they are big shoes to fill. "Ana was a great casting choice as she captures Marilyn’s glamour, humanity, and vulnerability.”
Armas herself told The Sunday Times that it took her nine months to learn how to speak like Monroe, and she said the process was “so exhausting.”
