I think that they honestly might have because Marvel Studios has never had any animated films under the MCU (this isn't 616, but still MCU), it would be after their first live action R-Rated movie (Deadpool & Wolverine) and first live action TV-MA show (Echo) also it would have a lot more marketing, and would've probably released in October.
If Marvel Zombies was a movie like originally planned, do you think it would've been released theatrically?
