On the subject of Sci Fi in the movies and on TV a colleague some years ago did a lecture on the Physics of Superheroes. 2 of his suggestions were
1 Supermans X-Ray vision would kill him because the heat generated in his skull by generating X-rays would cook his brain, he used the correct equations to show the energy produced.
2 that a motor cycle that had a particle beam weapon on it ,to raise enough energy for the beam to work as the show suggested would weigh several hundred tons, but, more importantly, be 3/4 of a mile long!!!
