Americans, how convinced are you by British actors such as Andrew Lincoln playing American characters?

Andrew Lincoln (Rick from the walking dead) Dominic West (Mcnulty from the wire) Aidan Gillen (the wire) David Morrisey (the governor from walking dead) Laura Cohan (Maggie from walking dead) Idris Elba (stringer bell the wire etc...) Lennie James (Morgan from the walking dead) Any of them you think do a... show more Andrew Lincoln (Rick from the walking dead)
Dominic West (Mcnulty from the wire)
Aidan Gillen (the wire)
David Morrisey (the governor from walking dead)
Laura Cohan (Maggie from walking dead)
Idris Elba (stringer bell the wire etc...)
Lennie James (Morgan from the walking dead)

Any of them you think do a particularly good job with the accent or any that you think sound phony? Not just from this list, whoever you can think of.
