Re: Character Accents: Should they be used?
It's too late now for established characters.
Alan Cumming did a very good German accent, it was recognisably German but cleverly still kept the English 'w' pronunciation rather than turning 'w' into 'v' (as in when he said 'I could wind up inside a wall').
I hope we don't see Fassbender lapsing into Irish again. I keep wondering why no one made him do the scene again with the proper accent! It must have been done in a real rush, that's my only conclusion, or he would have been asked to do the scene again or at least overdub it with the right accent. It's really jarring when he sounds more and more Irish at the end of the movie.
