If you thought Disney was slowing down theatrical to focus on putting Disney+ over, think again. I'm not sure how legit this information is because I've only seen it on twitter but it comees from a Buzzfeed editor with a "verified" check so perhaps. Weird that there hasn't been major trade coverage at this writing but here we go. Supposedly Disney has released their schedule for the next 4 years (what?) though one must view the titles and dates with a healthy dose of skepticism since, for example, Avatar sequels are pure illusions and the world will surely end before we get them. Also though there are a few Fox Searchlight titles listed that mini wing's releases are always decided much later since they regularly pick up films from festivals that they think have awards potentials and so you never know about those in advance. Okay the list goes like so...

After 2020 it all starts to get a bit silly with lots of untitled date claiming. But 2021 has some films of course since they're going to have to start shooting soon.
