Can't this guy lose his accent?
He's supposed to be an actor, isn't he? Lot's of other European actors manage to speak English without an accent. My ex is from Sweden, she came here when she was 25 and she had virtually no accent within about 20 years and she's not even an actor.
It's totally unrealistic for most of the roles that he plays. Remember when he played the governor of California (sorry, I don't remember the film)? Like the governor of California is going to have an Austrian accent.
