In theory, everything is connected in the Marvel Cinematic Universe, but in practice, that hasn’t quite panned out as fans may have hoped. Still, there may be a glimmer on the horizon for Marvel’s Inhumans, the new film-turned-TV series that will premiere in IMAX theaters before continuing on ABC. In a new interview, the show’s pilot episode director Roel Reiné (Death Race 2) said that Marvel seriously wanted Inhumans to “tie in” with other characters “in other universes,” whatever that means.

“There was always a Marvel executive around me,” Reiné told CNET in an interview, which he said was “to make sure that whatever I did, or whatever we did together, would tie in with other characters in other universes, in other comics, in other series or movies.”

“They’re very protective,” the director added. “These people are very passionate about their product and about characters and about doing the best version of everything.”

Good to know that Marvel is passionate, but what does Reiné mean by Inhumans tying with other characters and universes? Is Inhumans expected to have a gateway to Fox’s X-Men continuity? That’s hard to believe since the MCU can barely cross over with itself.

In the MCU, major events are what keeps the universes together. The climax of The Avengers (2012) had a huge impact on properties like Daredevil and Luke Cage on Netflix and this year’s Spider-Man: Homecoming. But it’s unlikely Ghost Rider ever gets to talk magic with Doctor Strange, or Jessica Jones gets to outdrink Tony Stark. (Can you imagine that one happening, though? It’s so good.)

And it’s less likely that any MCU hero will guest star in Inhumans, aside from maybe Agents of S.H.I.E.L.D. — which happens to be the one Marvel show its own star acknowledged that the company “doesn’t seem to care” for. Set in Hawaii, Inhumans will follow the Inhuman king Black Bolt (Anson Mount) as he is exiled from Atillan to Hawaii, a place where the MCU has never visited since it’s birth in 2008.

Marvel’s Inhumans will premiere in IMAX theaters on September 1 and will air on ABC on September 29.
