Insultingly Stupid Movie Physics. A brilliant little website with this to say :-

"In the name of physics decency, to protect the minds of children everywhere, so that they may grow up in a world where they know the difference between speed and velocity, we have taken the responsibility to rate movies for their portrayal of excessively bad physics."

"The motion picture industry has failed to police itself against the evils of bad physics. This page is provided as a public service in hopes of improving this deplorable matter. The minds of our children and their ability to master vectors are (shudder) at stake."
