As much as people are hoping for a Hulk standalone movie, lead star Mark Ruffalo said that it is not happening anytime soon because Marvel still has to iron out some intellectual kinks.

"I think they've been working on it. Marvel and Universal famously don't get along very well, and so that's working against us, definitely. But I know for a fact that everyone is holding out hope that one day we can do it," he shared with Yahoo! Movies. "But the nature of the relationship right now, it's a little prohibitive. And I hope that that changes, that changes with regimes, it changes over the course of time. But right now it doesn't look particularly promising."

Ruffalo said that the two studios are very eager to strike up a happy compromise; however, they are having difficulty in doing just that.

"I think ultimately that's what they're after, it working out for both sides. But like I said, Marvel and Universal are just not having a good time together right now," he said.

After Ruffalo's Thor disappeared in "Avengers: Age of Ultron," people are wondering where Marvel is taking his character next. The actor is heartbroken that he won't be a part of the next Marvel film "Captain America: Civil War," since most of his Avengers co-stars will be a part of it.

"They're saving me, so I'm told," said Ruffalo.

What has been confirmed though is that his character will be back in Chris Hemsworth's Thor's third standalone film "Thor: Ragnarok."

When asked about any updates regarding that film, Ruffalo answered: "They're still writing the script. That'll start shooting this summer. In June. There's still a lot of work to do on that."

Disney's "Star Wars: The Force Awakens" was heavily cloaked in secrecy, and when asked if Marvel employs that same level of security when it comes to their plots, Ruffalo said that they are pretty similar.

"I don't know if it's as secretive as that, but it's pretty secret. They definitely don't want people to know what was going on for a while. I've been sworn to secrecy, to the point where they don't even tell me. And they keep an eye on you. You might get a call," he said. "I tend to walk dangerously close to the line, as I generally have since I was a young boy, and so you do get the calls, like, 'Okay, let's be a little careful here.'"
