A couple of days before the Thor: Ragnarok premiere (so before any audio from the movie is accidentally live-streamed), Mark Ruffalo said that there were big plans in store for Bruce Banner/Hulk. The actor explained that since there can't be a Hulk solo movie in the MCU, the character will have a three-story arc that starts in Thor: Ragnarok and ends in the still-untitled Avengers 4.

This inspired fans to speculate about a possible big-screen adaptation of World War Hulk. It remains to be seen whether that will happen, and if it does, it remains to be seen what will cause the other guy to turn on his fellow superheroes.

That's a lot of ifs. But one thing is certain: We’ll see Hulk evolve, beginning with Thor: Ragnarok, in which he can actually talk!

Screen Rant asked Kevin Feige about how Hulk's story will progress and whether we’ll see another side of the character. He replied that he couldn’t answer the question (which in itself might be a hint). However, he did confirm the three-story arc, and said that it would resolve the issues between Banner and Hulk:

Anything's possible. When we were talking to Mark about this movie, and trying to get him excited, and getting him to agree to be in this movie, I did pitch to him a potential, sort of three-movie arc for the character, starting with this, and that is what we ended up doing. Now, I won't say where it goes, but it's the continuing evolution of the relationship between Banner and Hulk, and you see a side of it here. There's a great line. He [Banner] says, "It's different this time. Usually, it feels like we both have a hand on the wheel, but this time he was driving and I was locked in the trunk." Are they ever going to be able to resolve that?

Did this quote set off an even more spirited conversation about everything heading toward a World War Hulk adaptation? Of course it did! What do you think? How could the MCU reach that point?
