Mark Ruffalo to Play Hulk in The Avengers?

We’re guessing that Marvel Studios was hoping to announce this at the San Diego Comic-Con on Saturday, July 24th, but Deadline is reporting that the studio is in "late-stage discussions" with Mark Ruffalo to play The Incredible Hulk in The Avengers, scheduled to hit theaters on May 4, 2012.

He would be replacing Edward Norton, who played Hulk in director Louis Leterrier’s The Incredible Hulk. Marvel Studios’ Kevin Feige and Norton both confirmed this week that he would not be returning for The Avengers.

Can Ruffalo top Norton’s performance? Watch the trailer for The Incredible Hulk below:
