NOTE: THIS IS NOT A REVIEW BUT GOOFS I WANT TO REPORT!

Rating: Null/10 (5 May 2003)

Goofs:
(Continuity):
When William Stryker notices the dam is leaking he looks up, takes off his glasses and a drop of water falls on it. When the camera zooms in on his hands holding the glasses there is no water on the glasses. And Stryker could not have wiped it off first (since the footage is supposed to be continuous).

(Factual Errors): Magneto's cell is completely metal-free so he is not able to control anyone who is wearing metal. When Stryker comes in he wears his regular glasses (the pair he is wearing throughout the entire movie). Although it is hard to tell, but close inspection of the glasses point out the glasses contain metal. At least the bridge over his nose and the legs contain metal. The glasses probably also contain metal screws.
The guard, who is seduced by Mystyique and eventually killed by Magneto in his cell, also has badges on his uniform held by metal buttons.
