Inhumans was one of the many movies announced as part of Marvel's 2014 Phase Three slate, but last November, Marvel announced they would take the project on a different path by making it into a TV series for ABC. Given how prominent Inhumans are on Agents of S.H.I.E.L.D. nowadays, this decision does make sense, but there are undoubtedly a fair amount of fans who were looking forward to seeing these superpowered characters on the big screen. Vin Diesel, a.k.a. the voice of Groot, is one of those people, and he believes Marvel shouldn't scrap plans for an Inhumans movie. As he sees it:
I think Marvel should never---I don't think Marvel should abandon their opportunity to make a film out of it. I think it could be a huge, huge saga, and if I had more time I would go over to Marvel and have that very conversation. But I think it would be a big mistake for Marvel to abandon their ambitions or their objective or their goals of making it into a film, because it would make such a cool universe.
During an interview with Screen Rant, Vin Diesel was asked how he felt about Inhumans movie to television, and while it doesn't sound like he has any problems with this small screen approach, he also doesn't want Marvel let go of the chance to use these characters in a movie as well. Of course, it's worth noting that Diesel has some personal interest in this, because for a while, he alluded that he would play Black Bolt, the mute head of the Inhuman Royal Family. Since the Inhumans TV series is confirmed to star members of that family, it's unlikely Diesel will still be able to score that role unless he agrees to put his movie career on hold and take a pay cut. Nevertheless, even if Black Bolt is off the table, Diesel is keen on seeing this corner of the Marvel universe get its due among the likes of Iron Man, Captain America, the Guardians of the Galaxy, etc.
The Inhumans were officially introduced to the Marvel Cinematic Universe halfway through Agents of S.H.I.E.L.D. Season 2, and thanks to a Terrigen outbreak across the world in the Season 2 finale, their numbers skyrocketed. Some of the show's notable Inhuman players, both good and bad, have included Quake, Lash, Yo-Yo and Hive. Looking at the MCU as a whole, i.e. movies and television, Inhumans seem to be the most common group of super-powered people on Earth, so the longer they go unaddressed on the big screen, the weirder the silence is. That's not to say Marvel is obligated to release an Inhumans movie after a few seasons of the TV series have aired, but this race of altered humans should at least be addressed at some point in Phase Three of Four.
Inhumans is scheduled to air on ABC in September, and the first two episodes will also be screened ahead of time in IMAX theaters starting September 4 for two weeks. Stay tuned for more updates.
