Ripped this off sum guy at aint it cool news sound believable:
Beck was a failed actor/stuntman, right? In the first movie he was working as an announcer, but this punk kid comes in, steals the name HE gave him, and then fails to stop a robbery which bankrupts the wrestling promoter, causing the announcer to lose his job. Then, in the second movie, he's found a job as an usher for a broadway theater, but this punk kid comes in and tries to enter after the show starts. The usher says he would "destroy the illusion" of the play. This is obviously Quentin's desire to stage true to life illusions. Later on Spider-Man is unmasked in front of a couple hundred subway passengers. Someone on that damn car had to have a cameraphone. A pic gets in the papers, the usher sees who it is, realizes it's the same kid who tried to ruin the illusion AND stole the Spider-Man names AND lost him his job and there you have it: the man villain for Spider-Man 3 is Mysterio. But then again I forgot to wear my tinfoil hat today, so the aliens might be making me say this.
