Willem Dafoe is currently in talks to replace John Malkovich as the villainous Green Goblin in Sam Raimi's upcoming Spider-Man movie, according to a news report from Variety.
Malkovich dropped out of Spider-Man in a dispute partly over compensation. That, and I believe there were other ideals in which Malkovich argued about, principally concerning the creative and commercial aspect of the film itself.
Now, Dafoe would play industrialist Norman Osborn, who becomes the Green Goblin after an experiment goes wrong.
And recently, Dafoe starred opposite Malkovich in the upcoming Shadow of the Vampire, a fictionalized account of the making of the silent vampire film Nosferatu. I remember seeing the previews to that movie in the theatre, and it definitely looks worthwhile.
