"We have really great people though as the villains in this film, Thomas Haden Church and Topher Grace -- Venom and Sandman," said Dunst, who plays Mary Jane Watson in the Spidey films. "Maybe I wasn't supposed to say that," she added before reversing her claim. "It's the other way around. You're right," she conceded to a journalist. Dunst has yet to receive a script for the third film that will begin shooting in January. "But I know the general story. There's a lot that they're trying to fit into this one."
