15 Announced Movies That Are Destined For Development Hell
8. Inhumans
Status: After Marvel Studios stated their intent to add Inhumans to the Marvel Cinematic Universe back in 2014, it was recently announced that the July 12, 2019 release date will be delayed to an undisclosed one.
Why It's Going To Development Hell: Because the movie has already been delayed in the past, Marvel Studios have other pressing movies to address (like making Spider-Man successful again), and taking away the big niche that's making Agents of S.H.I.E.L.D. stand out could be a major mistake.
Consider further that Marvel haven't offered up an alternate release date yet, likely because they're still trying to figure out exactly when they're going to have the time to devote resources to the film, especially when Phase Four will likely see a number of major MCU roles being recast, at which point Kevin Feige and others may need to put their energy into getting that right instead.
We're not massively bothered about this one, especially as superhero fatigue is very real, and this kinda material feels fairly well-trodden by Guardians of the Galaxy.
