When asked about the possible return of MJ played by Kirsten Dunst Raimi states:
“Kirsten? I have talked with her, and she's very excited about the possibility of it,” I think I'm going to have to read the screenplay and make sure everything we've talked about is working, before I could honestly tell you absolutely how [MJ's return to the big screen] would go.”
When you ask, when will Raimi finally see the Spider-Man 4 script? Raimi has indicated it could be as early as June.
This from Sam Raimi, “Right now, David Lindsay-Abaire, a New York playwright, is working on the screenplay. He says that he'll be done in about four weeks with his first draft. So that's where I am right now. And I'm just about to hire a production skeleton.”
