Today could have been a very cool day for fans of the Marvel Cinematic Universe. Not that it's a bad day or anything like that, but it's not as cool as it could have been, as today would have been the day that the Inhumans movie would have arrived in theaters, had things gone according to plan. Yet, we're not getting any such movie today, or any day in the near future. And certain fans are taking to Twitter to mourn the loss of what could have been. So what happened exactly to derail this potentially awesome project?

Back in October 2014, Marvel Studios made a huge, splashy announcement debuting their upcoming slate for what we've come to know as Phase 3 of the MCU. That included Captain America: Civil War, Doctor Strange, Guardians of the Galaxy Vol. 2, Thor: Ragnarok, Black Panther, Captain Marvel, Avengers: Infinity War Part 1 and 2 (which eventually became Infinity War and Avengers: Endgame) and Inhumans. While most of that came true, Inhumans wound up on the scrap heap.

July 12, 2019, was the date that had originally been slotted for Inhumans. It's unclear exactly how far development got on the project, but when it was revealed in 2016 that the characters were going to be the subjects of a live-action series on ABC, everything changed. As a result, people have been posting on Twitter to commemorate the would-be occasion, such as this from Justin Scuiletti.

"Somewhere in the multiverse we could've been watching "Inhumans" in theaters tonight."

Marvel Studios has always had something of a disconnect between the TV side of things and the movies. While shows like Agents of S.H.I.E.L.D. (which actually introduced the idea of the Inhumans long before the would-be movie) take place in the MCU, they've always, more or less, existed in their own little corner of the universe. So, when the characters started to appear on Agents of S.H.I.E.L.D. and were subsequently given their own series, it made the movie seem redundant. Not to mention that ABC's Inhumans TV show was absolutely panned, which didn't help matters any.

For those who may not be familiar, the Inhumans debuted in Marvel Comics back in 1965. The story centers on a royal family of super-beings ruled by their silent king Black Bolt, whose voice is capable of destroying cities. Vin Diesel was rumored to play Black Bolt in the movie. The young members of the group are gifted their power from ingesting a powerful agent known as the Terrigen Mist.

The question becomes, could we ever see Black Bolt and the rest of the family make their way to the big screen? Absolutely. Very little has been revealed about Phase 4 of the MCU and the possibilities are virtually endless. Not to mention all of the shows being developed for Disney+ that will be more firmly rooted in the MCU. Maybe Kevin Feige and Co. can give it a more proper attempt down the line? It's up to the powers that be at Marvel now.
