The Hollywood Reporter is reporting that Nick Cassavetes is in negotiations to direct Marvel's Iron Man film, due out in 2006. Cassavetes had a weeper hit this summer -- The Notebook. To explain why a director with that kind of pedigree was right for a superhero movie, Marvel's Avi Arad pointed out to The Hollywood Reporter that Bryan Singer (X-Men) and Sam Raimi (Spider-Man) had both directed character-based film prior to their work on Marvel superhero movies. 'It all starts with the emotional mix,' Arad said.
