"Captain America: Civil War" has a pretty long roster of heroes so far -- everybody from Ant-Man to the Winter Soldier will show up to bust some heads. But what about the Hulk? Will he ever come back from running away at the end of "Age of Ultron" and join a side?

Not so, according to Mark Ruffalo. In an interview with the Italian film website Badtaste.it, Bruce Banner himself let slip that he was reportedly intended to make an appearance "Civil War," but that script rewrites removed the character from the film.

Here's what he said, as translated by an Italian-speaking employee over at Vulture:

"I believed that [Hulk] would be in the film, but at the end, it was evident that they needed to reveal that the Hulk did something very significant, and that Marvel wanted to use this in a more upfront [manner]. My character was inserted into the script, but it was later removed. Who knows, maybe Hulk will never return. However, [Marvel] want to keep the revelation of what happened a secret, because it is something truly significant."

More significant than hijacking a Quinjet and disappearing after a giant battle with Ultron in the last "Avengers" movie? That's got to be pretty big. Fingers crossed that maybe this means Bruce is closer to getting his own "Planet Hulk" movie soon -- though given all the confusion surrounding the rights to a solo-led Hulk movie, we'll probably still be waiting a while.

"Captain America: Civil War" hits theaters May 6, 2016.
