It took three tries and three actors, but we now have a Hulk we finally want to see in his own solo films.
So naturally, we have no idea when that will happen. It’s certainly not part of Phase Three, and it’s hard to say where Hulk would fit in anywhere other than an Avengers movie. He’s such a singular character, and if you send him rampaging through Black Panther and Captain Marvel, you could easily overshadow those new characters.
However, putting him in his own movie presents its own difficulties as well. Speaking to Empire, Mark Ruffalo said he was unsure of when we’ll see another standalone Hulk film, although he adds there’s a developing dynamic with Bruce Banner and “the other guy,” in Avengers: Age of Ultron:
“Who knows where these things will go,” says Rufallo, “but as Bruce is able to impress his will on the Hulk – going into The Hulk and being inside the Hulk when he’s raging – The Hulk’s will is also growing and able to impress upon Bruce… It’ll be interesting to see if that ends up being what would be the next Hulk movie.”
But Ruffalo adds that no one has talked to him about another Hulk film, and he acknowledges the difficulty of making one:
“[A new feaure-length Hulk movie is] a tough nut to crack,” Ruffalo confesses. “Traditionally you’re watching a guy who doesn’t want to do the very thing that you want him to do. It’s hard to take for two hours. I don’t know how many times you can use that same framing for it, but now he’s maturing and there’s a cool dynamic growing between Banner and The Hulk.”
When it comes to a new Hulk movie, some fans have been clamoring for an adaptation of the comic Planet Hulk which could then lead to World War Hulk. In the former, the Illuminati (a secret organization that contains Iron Man, Black Bolt, and Doctor Strange among others) decide that Hulk is too dangerous to remain on Earth, so they trick him into going into space and then they jettison him to a distant planet. When he’s there, he becomes a conquering hero. World War Hulk has him returning to Earth to take revenge.
If you want to get super nerdy on how to twist this into a potential storyline for the films, you could set the seeds of it in Avengers: Infinity War, and then build Phase Four around Hulk with Planet Hulk set in the middle of the phase, and then the culmination being Hulk versus the Avengers. It would be an interesting development to see a team of Avengers fight an outsider like Thanos to battling one of their own (although we’ll get a glimpse of that in Avengers: Age of Ultron when it’s Hulk vs. Iron Man’s Hulkbuster armor).
