I saw Mel Brooks' first movie "Producers" i s probably one of the best movies making fun of nazis I have seen in a long time. Some producer comes up with the ultimate sheme to put up a musical nobody wants to see and cash off from it. He buys a script for a Hitler-musical and lets some gay pothead called LSD play Adolf. But then Springtime for Hitler becomes a great hit! Deutschland is happy and gay. Hilarious movie if you can catch it on late-night tv or something like that!

It's also a huge hit on broadway by now.
