The next Spidey movie is supposed to feature 2 villains instead of just 1. We'll see how that works in practice.
The Batman movies did this for the last three installments, and Batman Begins did it as well. Prior to batman Begins I thought this was a fairly dumb idea as it burned through the characters twice as quickly without really providing much more than a lot of one-upmanship in the scenery chewing department (see Batman Forever... or, rather, don't...).
At any rate, looks like occasionally popular actor Thomas Hayden Church will be playing Spidey mainstay, The Sandman. he was signed a long time ago, but it was never made public which character he would take on.
Well, please see below:
Who is the other villain? Surprise, surprise... the rumor mill is saying "Venom" as played by Topher Grace.
