Still missing a LOT of legacy content besides the new ones tied to Netflix and HBO from Disney and Fox respectively.
Off the top of my head:
- Most Fox Stuff (PG-13 and lower)
- Any Home Alone movie
- Anastasia
- Blue Sky movies
- Fox Animation movies (Simpsons for example)
- Sandlot 2, 3
- Alvin and Chipmunks
- Greatest Snowman
- Planet of the Apes movies
- Malcolm in the Middle (announced back in April, but not there for launch)
- Office Space
- Avatar
- Etc
- Touchstone/Hollywood (PG-13 and lower)
- Signs
- Sixth Sense
- Gone in sixty seconds
- Armageddon
- Wild Hogs
- Arachnophobia
- Spy Hard
- Etc
- Disney
- Pirates of the Caribbean Dead Men's
- Bedtime Stories
- G-Force
- Dinosaurs (90s TV show)
- TinkerBell movies that are currently on netflix
- Short film collection currently on netflix
- Marvel (PG-13 and lower)
- Lot of MCU movies
- Non MCU movies like the X-Men ones from Fox
- Star Wars
My guess is that a lot of these are still tied up in current contracts. However I also think that Disney will play it in a way to have a second and third wave of new movies and tv shows coming to the service. That will keep the hype up and drive new subscriptions IMO.
Some of these might go to Hulu as they are "harder" PG-13 movies like sixth sense and signs, but they have a lot of content still missing that will most likely be coming in the next few months and years.
