On the subject of commentaries listen to the one on 'The Sum Of All Fears'. The book was written by Tom Clancy and the bad guys were arabic. For the film it was changed to having Nazis as the bad guys and other cuts were done.
Someone sat down Tom Clancy and the director together to talk about the film. Thing is that Tom Clancy is very knowledgable about the military. I don't think the director is and Tom gruffly picks holes in the film at many points.
While the Americans are looking over a Russian military facility you can hear this, they are talking about a missile being winched up in the background:
CLANCY: "Is that supposed to be a bomb or a torpedo?"
ROBINSON: "It's a bomb. Why?"
CLANCY: "The dimensions are wrong."
ROBINSON: "In that case it's a torpedo."
CLANCY: "OK. The dimensions are still wrong."
Something else made me laugh later when he picks holes in the way a bunch of Russian pilots are sent to blow up an American carrier with no real briefing. They all just grab their gear and run out of the door.
