We’ve heard conflicting reports about Hulk’s involvement in Captain America: Civil War. Although he’s not on the official cast list, there have been reports he’ll actually make a brief appearance, and Robert Downey, Jr. even said Bruce Banner’s Hulk would show up. But it appears even Iron Man doesn’t know everything, as Mark Ruffalo, who plays Hulk, has said he’s not actually in the film.

Well, let’s back up: Hulk was going to be in the movie, but Marvel apparently thought his story arc was best saved for a future film. Here’s what Ruffalo had to say:

I thought that I would be in the film, but in the end [Marvel] evidently believe that the reveal of what happened to the Hulk was too big, and Marvel wants to save that information for later. My character had been in the script, but then he got removed. Who knows, maybe the Hulk will never return. They want to keep the revelation of what happened to him a secret, because it’s something really big.

Since Civil War is already packed with pretty much every Avenger, it sounds like Marvel didn’t feel it had enough time to explain Hulk’s story. His disappearance is currently one of the biggest cliffhangers in the MCU, so it will be very exciting to see where he’s run off to. We’re not sure what Ruffalo is teasing when he says “it’s something really big,” but perhaps a post-credits scene will help fill in the blanks.

If Hulk doesn’t make an appearance in Civil War, then when the heck are we going to see him next? The next few Marvel films include Doctor Strange (Nov. 4, 2016) and Guardians of the Galaxy, Vol. 2 (May 5, 2017), so there are some interesting possibilities. We could potentially see Bruce Banner meet Doctor Strange in an effort to rid himself of the Hulk. That would be a nice segue to introduce Doctor Strange as part of the MCU, and ultimately as a member of the Avengers.

Marvel recently unveiled the “teams” in Civil War, and we also talked at length about what to expect when the movie hit theaters on May 6, 2016.
