Universal Soldier (1992)

Revealing mistake: Towards the end of the movie where Veronica Roberts hands are tied behind her back, she goes over to the mulching machine to cut the rope free. But as she hits the blades they bend and move like rubber.

Veronica: How can you be so damn calm? I mean, your buddies back there just shot enough ammo at us to destroy Eastern Europe, and you're sitting here bitching at me about a goddamned seat belt?
