It's been hard for Marvel to found a stable Hulk franchise in recent years. A decade ago, Eric Bana filled Bruce Banner's shoes in Ang Lee's Hulk, which received mixed reviews. More recently, Edward Norton took a stab at becoming the Hulk, but abandoned the role soon after.
Mark Ruffalo signed on to star as Bruce Banner in last year's blockbuster The Avengers, and it seems that the actor might be in for the long haul. Unfortunately, that may not mean that Ruffalo will star as the Hulk in an individual movie franchise.
Yesterday Ruffalo revealed through his Twitter feed that there are no current plans for a new Hulk movie, and that the next time he will appear as the character will be in the sequel to The Avengers.
A lot of folks have been asking about the Next Hulk. The next time you see my Hulk it will be in the Avengers2. No plans for stand alone.
I am not giving up on another stand alone HULK. But it’s not in the works right now. One never knows what the future will bring.
Ruffalo later reemphasized that his statement doesn't mean there will never be another Hulk movie:
Just to be totally clear. I did not say there was not going to ever be a stand alone Hulk film. I said there wasn’t one in the works now.
Ruffalo's tweets back up a comment made by Avengers director Joss Whedon in a recent interview with IGN. Whedon shot down rumors that the next Avengers movie would focus on the Hulk.
