Good acting is all about making the audience believe in your character. While this can usually be achieved through some deeper understanding of the role they’ve been cast to play, there’s one facet to acting that many actors believe themselves to be better at than they really are: accents.

A good accent is a thing of beauty, and lends an auditory authenticity to a role. A bad accent, though? Well, they’re just laughable.

We can only guess at the reasons behind these awful accent attempts, even as we laugh at the results. But here are 7 of the worst accents ever committed to film.

7. Charlie Hunnam – Green Street (2005)

Despite being from Newcastle, Hunnam has one of the strangest natural accents going, because it doesn’t quite fit anywhere. It’s a bizarre blend of what should be his natural Geordie accent with an American twang that seems to place the origin of his voice smack-bang in the middle of the Atlantic. Point is, Hunnam’s accent is odd at the best of times.

In 2005’s Green Street, however, Hunnam’s attempt at sounding like a cockney football hooligan was just plain unpleasant. In fact, it’s so bad, it’s obvious even to a non-British audience that it missed the mark in a major (and borderline offensive) way.

Considering he was born and raised in the UK, his inability to even approximate a cockney accent is more than a little disappointing, and the results are not easy to watch (or hear).
