"Although it's not really news that Spider-Man 4 will start shooting in 2010 as this report at MTV highlights (director Sam Raimi himself said previously that filming would start by March of 2010), it is good to hear that J.K. Simmons will be returning:
The fourth film in the blockbuster 'Spider-Man' franchise will begin shooting in 2010, actor J.K. Simmons told MTV News at Sundance, revealing that he'll continue in the role of Daily Bugle publisher J. Jonah Jameson. 'I saw Sam [Raimi] at his Christmas party.'
The fourth installment is expected to hit theaters in May of 2011. In October of '08, it was announced that playwright David Lindsay-Abaire (upcoming Inkheart) would write the script. James Vanderbilt wrote an earlier draft."
This is great news! I can't wait to hear, "PARKER! GET IN HERE!" on May 2011.
P.S.: I think it's noteworthy to add that Tobey Maguire has also signed up for a Spider-Man 5. What could happen?
