Inhumans is getting pushed back in the Marvel Studios schedule.

The most recent plan was to have the movie, about a race of hybrid alien/human superbeings who live in their own world, released in theaters on July 2, 2019. Marvel Studios president Kevin Feige, who has been talking about the movie for years, now says he expects the movie to be delayed.

The reason for the change? In the time since the Inhumans movie was announced in October 2014, Marvel Studios has added a number of new projects to its lineup, including a partnership project with Sony Pictures for a 2017 Spider-Man reboot with Tom Holland as the webslinger. (Previously, Sony held the license for the character, which meant the Tobey Maguire and Andrew Garfield films weren’t included in the larger Marvel Cinematic Universe. That changes with Holland’s Spidey being part of next month’s Captain America: Civil War.)

With new projects like that in the slate, along with a sequel to last year’s Ant-Man — and concerns about bumping into other films released by their Disney parent company — Feige says that 2019 Inhumans date is going to change. But he insists it is not being canceled, even though they have been exploring Inhumans characters on the Marvel TV side in ABC’s Agents of S.H.I.E.L.D.

Feige says the Inhumans movie will happen, it’s just a question of how far back it will be delayed.

“Since we made our initial phase three announcement, we added Spider-Man, which was a big joyous coup for us. We added Ant-Man and the Wasp, which was a big fun continuation of that story for us. Walt Disney Company has announced an Indiana Jones film for right around that same time. So I think it will shuffle off the current date that it’s on right now,” Feige said in an interview with Collider‘s Haleigh Foutch. “How far down it shuffles, I’m not sure yet.”

The Inhumans comics, first introduced in 1965, focuses on a royal family of super beings, ruled over by their mostly silent king Black Bolt, whose voice has the power to level a city. Young members of the Inhumans family get their powers by venturing into the mutating Terrigen Mists to emerge as something different — and perhaps better — than what they were.

“Inhumans is cool, they’re really great characters,” Feige told EW in a 2013 interview. “The most powerful guy is the king who doesn’t say a word and if he does — lookout. That’s awesome. And the notion of the Terrigen Mists, this notion that you go through and don’t know what you’re going to be on the other side, is incredibly compelling dramatically.”

It would be an otherworldly story, akin to Guardians of the Galaxy, exploring the cosmic side of the Marvel Cinematic Universe, Feige told EW. “In other words, all the craziness that comes with Inhumans, we’ve done in the other movies already,” Feige said. “But this would have some of the social drama that we haven’t really done yet. [Fox’s] X-Men, obviously, has been touching on that stuff for a while.”
