Sony shows signs of moving forward with Spiderman 4. Personally, I would be disappointed to see this without Toby Maguire, but if its done right,(and the anti-Toby fans insist it could) I will line up to any Spiderman movie with Raimi directing. Of course that is up in the air as well.
Sony, however, seems to have a hard time letting go of their cash cow and has signed writer David Koepp (INDIANA JONES 4) to write a script for a fourth film. The studio hopes the film would be released in 2009 and 2010.
So to add emphasis to a movie that seems in negotiations limbo, they hire a guy slated to write the movie that will never happen.
Personally, I have resigned myself to the fact that Dunst doesnt want to (and the fans seem to disagree with me about her being a good MJ) and they look to replace her as the love interest with Bryce Dallas Howard as Gwen Stacy. This is backwards from the comic books, as Stacy dies at the hands of the Green Goblin, and then he moves on to MJ.
This gives them a convenient out for Dunst, and a fresh slate to hire on new cast.
The mighty dollar will of course decide in the end, as Sony still stands to make a heap of money from this no matter what they do to the cast. At least one more time.
