Spiderman 4

 David Lindsay-Abaire, who won a pulitzer prize for his 2007 Broadway play Rabbit Hole has signed to write the screenplay for Spider-Man 4.   Abaire was also responsible for the CGI atrocity that was Robots, but lets not hold that against him.

James Vanderbilt, writer of Zodiac was previously reported to be involved in the project, but no word on how far his script progressed.  

Raimi and Tobey Maguire have already signed up for the 2011 sequel, with Kirsten Dunst also expected to return.
