It doesn’t matter how famous a Hollywood actor you are, if the accent ain’t right, it’s just plain obvious. Our guest writer Sabrina Dougall from London shares her top 10 worst accent imitations in cinema:

1. Dick van Dyke (Bert/Mr. Dawes Senior) – Mary Poppins

2. Meryl Streep (Lindy Chamberlain) – A Cry in the Dark

Convincing emotional drama? Yes. Convincing Australian accent? Definitely not.

3. Brad Pitt (Heinrich Harrer) – 7 Years in Tibet

‘Nuff said. Did Brad really expect to get away with this one?

4. Sean Connery (Jimmy Malone) – The Untouchables

That supposedly Irish-American accent done by a Scotsman was never going to pan out well… No cigar, Connery.

5. Josh Hartnett (Brian Allen) – Blow Dry

Offensive to the ear – that California accent was painfully evident in Paddy Breathnach’s frisseur romcom.

6. Natalie Portman (Queen Amidala/Padmé) – Star Wars Episode I: The Phantom Menace

The Black Swan star starts off here with a British accent as Queen Amidala, then blunders into an American one when she’s Padmé…oh dear…

7. Paris Themmen (Mike TeeVee) – the original Willy Wonka and the Chocolate Factory

Begins well as a bratty kid from Arizona, but admits that he was messed up by hanging out with the other British actors. “Am I coming in clear?” was the unfortunate and ironically memorable line.

8. Leonardo DiCaprio (Danny Archer) – Blood Diamond

You tried, you failed. Better luck next time.

9. Hugh Jackman (Logan/Wolverine) – X-Men

Supposed to be a Canadian accent. Did you get that? Neither did we. Born in Sydney of English parentage, the H-man didn’t really stand much of a chance.

10. Jude Law (Inman) – Cold Mountain

The British babe falls just short of the mark with his less-than-convincing Southern accent. Down-Under co-star Kidman (Ada Monroe) also fails to deliver a credible US accent, creating lingual chaos in this Civil War romance.
