Several movies that were due to be released this Spring and Summer will be delayed, but Disney is already fast-tracking Onward to Disney+ and digital release, and I think some other films are following.
Should mostly "In the can" movies like No Time To Die and Black Widow follow perhaps (I'm guessing all that needed to be done was just some post work which I think can be done remotely without too much personal interaction)? NTTD was pretty much all set to go with the press tour already in full swing. BW also was starting to heat up and the action figure line just came out too I think.
A Disney+ debut for Black Widow would probably draw more people into the service. Not sure who has the biggest deal with Universal right now and who would release NTTD. Ditto with F9 although I'm not sure how far that was finished.
I mean, it would probably hurt movie theaters unfortunately but perhaps the films could be re-released later on the big screen with some extra incentive. "Endgame" for instance, got a re-release with some new content after the film (totally different situation though). Perhaps some kind of promotional program like that? Free snacks with every ticket? etc.
Again I'm not really an expert on economics or that sort of thing, just thought I'd throw it out there.
