good american accent

Only took a few scenes in the first episode of Flash Forward for his English accent to become obvious. Not nearly as bad as many, but not flawless

I agree, not flawless. Though I'm not a native English speaker, but I could tell from his very first words that he is not American.
I think the best American-speaking British actor is Matthew Rhys, he playes Kevin in Brothers and Sisters. And does it very well.


It takes the whole of life to learn how to live.

The best American-speaking British actor is Gary Oldman, hands down. And I'm American.

Forth, and fear no darkness!

Hugh Laurie seems to do a pretty good job in "House" too.

Nah, the best American-speaking British actor is Owain Yeoman from 'The Mentalist' who's Welsh :)

'Proud HSM Hater'
"That'll teach you to lick my muffin"

I couldn't even tell he was British. But maybe now that I know It will stick out more.

The director that hired Hugh Laurie of House did not know that he was English. I would say that if he didn't know, then that is a pretty damn good accent.
