It. Is. Time. From Victory Through Air Power to The Lion King (2019), check out basically everything *NOT* coming to #DisneyPlus in the U.S. on November 12.
The point of this thread will be to discuss and discover why certain Disney films are missing. This is not intended to be criticism. I'm sure there are good reasons as to why these films are missing and I'm curious if we can find out why.
If you know or have a good idea as to why any of these films are missing, please chime in. Also, I'm sure there are films that I will miss too. Please give me a day or so to post all of the films that I think are missing and then please let me know what I missed. Thanks!

Okay... I think that does it for theatrical releases by Walt Disney Pictures. Obviously, the last 15 or so movies in this thread were all released too recently for us to expect them on Disney+ on 11/12. I'd imagine most of them will make it there within the next year.
But we're not done yet! I haven't even started going through all of the thousands of direct-to-video movies that Disney has released since the 1980s. Many of them will be on Disney+ but I wouldn't be surprised if many are missing. Look for that thread soon-ish.
Finally (for tonight) let me put this earlier thread here to answer many of the questions I've been getting. I've also pinned it.
