A quick release-date update: Sony has revealed that Spider-Man 4 will be hitting theaters on May 6, 2011. Director Sam Raimi is on board, and I'd expect that with the original director back, Toby Maguire and Kirsten Dunst would sign on if asked. (Of course, Dunst may be on the outs.) With two years to go before the release, at least the overwhelming hype is still months away.
In other scheduling news, Marvel has racked quite a slate of superhero flicks for the next few years. The list is as follows:
Marvel Studios Feature Film Release Dates
Iron Man 2 May 7, 2010
Thor June 17, 2011
The First Avenger: Captain America July 22, 2011
The Avengers - May 4, 2012
Keep your eyes on The Avengers, a hybrid flick featuring many of the Marvel characters (Hulk, Iron Man) that have been drawing big dollars at the multiplex.
