Have you ever watched a movie and thought "hold on a sec, that wasnt like that a moment ago"
Commando was the best for it. The car chase when Arnie was chasing the creepy David Patrick Kelly and one second the car was all smashed up on the left side, then it was as new, then it was smashed, then as new. When Arnie finally got hold of him and hung him over the cliff, you could see the wire attached to DPK's foot. Also in Lethal Weapon 1, Mel Gibson chases the bad guy through a tunnel wearing cowboy boots but when he appears out the other end he is wearing trainers/sneakers. You can see a Jumbo Jet in the sky in The Flintstones too.
Any other movie mistakes that any of you can report??
