I've read that Mel Gibson was originally considered for the lead in Schindler's List. What if he had been cast, would it have led to an earlier anti-semitic outburst?
He could have the part of the camp commander that shot a woman that was squatting. If he said something anti jews i am sure the world would think it was a PR move for the movie at worst. I have a feeling though that Spielberg asked every actor and actress about their feelings towards jews before they got contracted to the movie
