I know this has been asked to death, but I need some examples of movies with bad physics?

When Hancock stops a train, violating the law of conservation of momentum.

Doesn't matter how strong he is, he doesn't have enough mass to stop the train. It's like a fly stopping a person. Also, any scene where a guy karate kicks another guy and sends him flying through the air. Newton's 3rd Law says that the kicker would be thrown back with a force equal to the kick. I believe the Matrix has a few of those scenes.

The Day After Tomorrow -think about the energy displacement it took freezing the East Coast so completely. Thermal dynamics would call for a massive influx of heat energy into the area.

Wanted- the trick shot bullets (curving the bullets trajectory). Mythbusters did experiments on this to see if it was possible. Come to think of it, they would have a lot of film blunders in their archives.

I may be thinking just a bit outside your box, but a movie I saw was brilliant !!

Exam:- Its a pyschological movie where approx 10 people are put into a room with strict instructions. In the meantime, they must turn their sheet of paper over and answer the question. But.......there is no question - its a blank sheet of paper, so what is the answer ?? They have to try and figure it out.
