Actor Mark Ruffalo told USA Today that a Hulk solo film feels "even further away."
"It's not Marvel's property, it's Universal's property," he continued. "I don't know. It seems really problematic."
The rights situation to the Incredible Hulk is thought to be unclear. A Forbes article from June of this year states that while Marvel obtained the film rights back from Universal, the studio still has "the right of first refusal" to distribute Hulk films. It's a subtlety that can get lost in an interview situation. Forbes also suggests this is not an insurmountable obstacle if the will was there to make another Hulk film.
If this is the case, it is also unclear why Ruffalo might think making a solo feature feels further away. Granted, he is not involved in the calculations that determine when characters get their solo films. And while he would certainly like to be the star of Hulk movie, Ruffalo said, "I've been around long enough to be OK with it. There's only so much that's in my power and I'm not going to agonize over what is not in my power. I definitely try to limit that to my kids and the things that really matter to me."
