This has in no way been confirmed by anyone directly associated with Marvel Studios, Marvel TV or Disney. But a new rumor coming out of NYCC 2015 is that Marvel Studios has decided to cancel the Inhumans movie due to a mounting war between their movie and TV departments. This comes after the ABC series Marvel's Agents of S.H.I.E.L.D. has laboriously tried to set up the Inhumans storyline. Marvel and Disney have not responded at this time.
Yesterday at NYCC, Disney announced its impending slate through 2020. Three new untitled Marvel movies were confirmed for 2020. And a number of titles got new release dates. Ant-Man and the Wasp took the July 6, 2018 release date, which pushed Black Panther to February 16, 2018. Captain Marvel moved from November 2, 2018 to March 8, 2019. Inhumans wasn't mentioned at all, and presumably, still holds its July 12, 2019 release. But inside sources close to Marvel and Disney claim that this sci-fi superhero adventure is being pulled from the slate. That would return http://tvweb.com/avengers-3-infinity-war-thanos-josh-brolin/Phase 3 back to its original 9 movie line-up. Of course, this all could just be drunk chatter heard late at night from a bar in the heart of New York City.
Early in September, it was announced that the movie side of things was breaking free from the rest of Marvel. Marvel Studios boss Kevin Feige was finally being freed from the Emperor like vice-grip of penny-pinching Marvel Entertainment CEO Isaac "Ike" Perlmutter. Though, the TV side of things remained under Perlmutter's super villain-like watch. This is said to have caused a major rift between the Movie and TV divisions. And it could mean the death of the Inhumans as a viable movie franchise. Though they'll continue to flourish on TV in Marvel's Agents of S.H.I.E.L.D. The series had already committed itself to three years of promotion for Inhumans. But Kevin Feige reportedly wants to get as far away from the movie side of things as possible.
This could have bigger ramifications. Many suspect that Marvel's Netflix series will eventually crossover with the movie side of the universe. Even Kevin Feige himself has said this is inevitable. But with a rift growing between the two departments, that might not happen at all. And various creatives, including director Joss Whedon, have expressed how hard it is to keep both universes connected. If things keep going down separate paths, the Marvel TV universe could become its own separate thing. Which might actually be better for all involved in the long run. And perhaps, Inhumans could become its own TV show if, in fact, the movie is getting canceled.
When Marvel Studios broke away from Marvel, the move signaled big changes for the way Marvel Studios is run. It will definitely give the MCU a chance to expand beyond the constricted shoebox Ike Perlmutter liked to keep it in. Though some felt it was a dangerous move. Up until now, Marvel has had nothing but success after success, with all of their movies hitting #1 at the box office on opening weekend. If the movies start to falter, Kevin Feige will be the only one to blame. But inside sources don't think there will be any problem. It remains to be seen at this point what will truly happen with the TV side of things in regards to the movies. But one thing is for certain, we probably won't see the Marvel's Agents of S.H.I.E.L.D. in Avengers: Infinity War if things keep moving at this speed.
