Guess who's up for Doc Ock in "Spider-Man 2"?

Andy Jones over at E Online has it from a reliable source that Robert De Niro could be up for the role of villain Doc Ock in "The Amazing Spider-Man". Jones adds, "Should DeNiro pass on Doc Ock, I hear Raimi pal Billy Bob Thornton is on standby–just in case. Another Raimi buddy, Bruce Campbell (The Evil Dead), has already been cast as the scaly, creepy Lizard in the Spidey script under way by Michael Chabon (Wonder Boys)."
