Warning: Spoilers
Quint from Harry Knowles' Ain't It Cool News posted an interesting diatribe on the Spider-Man 3 villain rumors.
Here's an excerpt: "The rumor says that BOTH Thomas Hayden Church and Topher Grace will be playing The Chameleon. The twist is that the shapeshifter has been this character warming up to Mary Jane on the sly as the affable Topher Grace. On the surface this sounds not only good, but pretty damn cool. However, wouldn't that make The Chameleon the main villain for Spider-Man 3? Isn't that a kind of weak follow-up to Doc Ock? And isn't The Chameleon a bad choice considering X-MEN's Mystique has been on screens doing the shapeshifting thing for almost 5 years now?"
Quint goes on to explain why he thinks the Sandman and Electro will be Spidey's foes in the film.
