I know I'm not the only one who thinks Hulk was the greatest part of "Marvel's The Avengers," just as I'm not the only one disappointed that another "Hulk" solo film isn't anywhere on the immediate horizon. But who knows what the future holds after the "Avengers" sequel? In fact, with all signs pointing to Earth's mightiest heroes embracing the cosmic side of the Marvel Universe, is it possible that we might see a live-action "Planet Hulk" in the future? Is that something Marvel could pull off?

"I don't think there's a lot that we couldn't do someday, as the cinematic universe continues to grow and expand and get as big as the comic book universe," Marvel's Kevin Feige told me when I asked him if we'd ever see a movie based on "Planet Hulk," the Greg Pak-written epic that sees the Jade Giant as a rebel leader on an alien planet, "Gladiator" style.

"'Planet Hulk' is a cool story," he added. "'World War Hulk' is a cool story."

There are a few obstacles that Feige sees in the way of any possible Hulk-in-space solo films. "I think there's pitfalls of continuity-overload, and mythology getting so dense that it almost collapses in on itself," he said. "It happens every few decades or so in the comics. Apart from that, I'd say everything is on the table."

Even if "Planet Hulk" or something similar is possible, there's no such movie coming any time soon. "Do I think Hulk can carry a movie and be as entertaining as he was in 'Avengers'? I do believe that. I do believe he absolutely could. We certainly are not even going to attempt that until 'Avengers 2,'" said Feige. "So there's a lot of time to think about it."

"Part of what's fun about the way we played him in 'Avengers' is the ensemble quality of it," he continued of why Hulk resonated with so many fans this summer. "I think the pathos and humor, most importantly, that Mark and Joss brought to it showcased a different element of Hulk that's there in the comics, and was always inherent in his character. But when he was so brooding in his other two films, he didn't get to have that wry sense of humor that Mark did such an amazing job performing."
