Mark Ruffalo and the rest of his Avengers: Age of Ultron cast mates completed the West Coast portion of their press tour this weekend. And on Saturday, the Hulk star revealed Marvel is still very much interested in doing a Planet Hulk movie. At some point, we'll get to see the green goliath travel into space. But in a new interview with Collider, it sounds as though we're more likely to see that plot happen as part of Guardians of the Galaxy 2 as opposed to the Hulk's own standalone movie. Apparently, the reason we haven't heard about a new Hulk solo adventure yet is because Universal Pictures still owns those rights. The actor explains:

"As far as a Hulk movie, a standalone Hulk movie, Marvel doesn't really have the rights to that yet. That's still Universal's property, so there's that issue. That's a big impediment to moving forward with that. Now I don't think that's insurmountable, by the way, but I don't know where it's going from here for me."

The actor reveals that, after appearing as Bruce Banner in 2012's The Avengers and 2015's Avengers: Age of Ultron, he still has four more movies left on his contract. Though, he has no idea what those four movies will be. As of now, he is not yet signed on to appear in next summer's Captain America: Civil War. And we may not see him again until Avengers: Infinity War Part 1 in 2018. About how many movies he has left, he says:

"I think it's four now, but that could always go further. That could include different-I could show up in another character's movie; I could do Avengers 3 and 4; I could do a Hulk standalone; I could do a combination of those things. That's four or five, I think. I don't know if I'm in [Captain America: Civil War] yet. I don't know. Sometimes these things happen at the last minute in this world. I really don't know where I fit in from here on out, and I'm not sure they do."

So, while Marvel can use Hulk in a shared universe movie like Avengers: Age of Ultron or Captain America: Civil War, a standalone movie will have to be distributed by Universal, with Marvel producing. Of course Disney isn't going to allow that anytime soon. Will Universal, Marvel and Disney be able to work out a deal much in the same way Sony and Marvel did with Spider-Man? We'll have to wait and see. Until that happens, will have to take our Bruce Banner as part of a team. Which some fans think works best anyway.
