With The Rock, Sean William Scott and Christopher Walken. A great movie, IMHO, but when I first started watching it I thought it was anti-gun. Boy, was I wrong. In fact, the message was "sometimes you have to pick up some guns and handle your business!" Great scene with The Rock and 2 pump guns. Fake, but great.
Plus, lots of good guns in that movie. MG42, BARs, M21, Druganovs, etc.
