Worst British accent by an American actor

[Journey]

Although it isn't a British accent, Colin Farrell in Daredevil.

I know what you're thinking, he's Irish and he has an Irish accent in the film. But that leads me to a question...

How is it even possible for an honest-to-god Irishman to sound like he's putting on an Irish accent?

The mind boggles...

i hate it when american actors use posh accents and say cheerio and think we only drink tea.
Only the royal family speak in a posh accent, coffee is more common than tea here and the last person who said cheerio was probbly beaten to death.
glad i sorted that out, so cheerio chaps!

my nana says cheerio all the time-were not posh-hell no but she still says it lol and i dont think she has been beaten to death

What about Don Cheadle in oceans 11? Got to be the worst accent ever, ruins the film.

My money is on Brion James, from Tango and Cash. He did the WORST damn cockney accent I've ever heard, or at least one of the worst.

And, this is slightly off-topic, but the worst accent I've ever heard, anywhere, is in the game Red Steel. The villains are japanese yakuza, and one of them has a terrifyingly bad accent. He goes from japanese to australian to british to american. It's quite strange.

Clive Owen in Sin City did the worst American accent by a British actor.  :doubt: or perhaps Simon Pegg in the Big Nothing.

As for worst British accent, I'd agree with whoever said Rene in Bridgit Jones. Damn I just admitted to watching it!
