Raimi says that he and the production team are “in the earliest stages of working with the writer, trying to work out a story.” He added that they are just working on the fourth installment and not also a fifth film. Previous reports had claimed that Sony Pictures would be making the fourth and fifth movies at the same time, but that doesn’t appear to be the case.
The helmer said that they are closing in on Spider-Man’s adversary or adversaries for the fourth pic. “All the characters or villains or villains, whatever we decide to do will be from Stan Lee’s creations or those that came after him,” he said.
And will Kirsten Dunst return as Mary Jane Watson? If it was up to Raimi, definitely: “Iâ€™m hoping she’ll be in it and I’m planning on having a story with her in it… It wouldn’t be the Spider-Man series without her.”
