Schwarzenegger in any movie where his character is supposed to be born and raised in America. Not as bad as the difference between Scottish/Egyptian but Sean Connery as the English King Richard in Robin Hood Prince of Thieves. And while I'm talking about that movie, what about Kevin Costner and his lack of an accent? Don't get me wrong, the movie has it's merits, but with so many English accents, his does stand out. "Unlike some other Robin Hoods, I can speak with an English accent." rofl Just a bit off topic here, but this was Alan Rickman's best performance aside from Galaxy Quest (not including Die Hard). Speaking of Die Hard, what do you think of his German accent?
