I was talking about the movie awhile back with my wife and mother-in-law, who are German, and interestingly, the main issue they had with Cruise in the role is that from their perspective he simply doesn't LOOK German. Like, at all. Granted, they're much more attuned to the ethnic variations among Europeans than I am, but they were basically saying Cruise is very stereotypically American in his bearing and features. I don't know what they'd make of the other actors in the cast on that ground, since Cruise is basically the only one that's figured in the ad campaign.
