As Dick Van Dyke publicly apologises for 'the most atrocious Cockney accent in the history of cinema' in Mary Poppins, we take a look at some other questionable accent attempts in movie history.

Van Dyke took the opportunity to apologise after it was announced that the British Film and Television Academy (BAFTA) would honour him with the Britannia Award for Excellence in Television.

"I appreciate this opportunity to apologize to the members of BAFTA for inflicting on them the most atrocious Cockney accent in the history of cinema," he said.

In case you need a reminder, here he is singing Chim Chim Cher-ee:

While Van Dyke's accent was pretty laughable, he isn't the only star to crumble at the task of adopting a new dialect.

Here's 10 other stand-out examples:

Kevin Spacey: Irish

We've listed the worst Irish accents in cinema before, so we'll just let Kevin Spacey in Ordinary Decent Criminal represent that section here. An incredible actor? Yes. A master of the Irish accent? Certainly not. 

Brad Pitt: Austrian

Giving the Austrian accent a go in Seven Years in Tibet, Brad Pitt manages to sound, well, just like Brad Pitt with a slightly different, un-placeable twang. It would make you wonder if his Italian accent in Inglorious Bastards was a legitimate attempt and not the scripted joke we're lead to believe.

Quentin Tarantino: Australian

Tarantino cast himself as an Australian man in Django Unchained, and it's one of the only flaws in an otherwise excellent film. Nothing's perfect, eh?

Michael Caine: Texan

He has one of the most distinctive voices in cinema, but outside of his own Cockney drawl he is less than exemplary. In On Deadly Ground, a 1994 flop, he gave the Texan accent a go and he doesn't sound like any Texan we've ever heard.

Angelina Jolie: Greek

Colin Farrell didn't attempt to go Greek for Alexander – the blonde hair was enough of a challenge to pull off – so we're unsure why Jolie, who played his mother, opted in. If the film wasn't set in Greece, we'd have no idea what she was going for here.

Jon Voight: Spanish

Another instance of genuinely not being able to figure out where the character is from by accent alone, comes in Anaconda courtesy of Jon Voight. He's supposedly Spanish, but we aren't so sure.

Keanu Reeves: English

Oh Keanu. Attempting an English accent in Dracula was not a career highlight for the Canadian star - it takes more than precise pronunciation to do it justice.

Josh Hartnett: Yorkshire

In Blow Dry, Hartnett sounded like he got very, very lost on his way to Emmerdale Farm. Certain words almost sound Australian, with the odd tinge of the man from the Ambrosia ad coming in too. 

Gerard Butler: American

He's previously apologised for butchering the Irish accent in PS: I Love You, but it seems like poor old Gerard just can't do accents full stop. Playing an American in Bounty Hunter, his own accent shone through for random words, with him choosing to just speak slightly slower, and lower, in other parts. There's more to it than that.

Mickey Rourke: Russian

Sounding more like a cartoon villain than an actual person from Russia, Mickey Rourke left a lot to be desired in Iron Man 2.
