Sometimes it makes more sense for Americans playing foreigners to just keep their native accents. Tom Cruise played a real-life German in
Valkyrie, and he didn't even attempt a German accent because it would have sounded ridiculous and distracted from the story. You can argue about authenticity all you want, but I think we're all aware that we're watching a dramatization, not a documentary.
On a somewhat related note, I'm frequently annoyed by the way that foreign actors are so often expected to fake an American accent in American movies. Is it really so implausible that a British character would be living in America? It especially annoys me when the actor is no good at doing accents. Sam Worthington, for example, is just miserable at doing American accents. Is there any reason his characters in
Avatar and
Terminator Salvation couldn't have been Australian? They might as well have been, since his accent kept slipping out constantly.
