And the rights to have X-Men, Deadpool, and The Fantastic Four into the MCU, which should be in Phase 4. Also, how could I forget Avatar, lol
They should’ve bought a portion of Fox, not the entire package.
They bought Fox mainly for the international infrastructure so that Disney's channels and streaming services could become a global powerhouse.
And speaking of streaming, the Fox library becomes a big chunk of content for Hulu and D+ (Simpsons!).
And speaking of new, original content for streaming, Fox had several movie and TV studios. The FX channel is a prominent brand now attached to Hulu. All of the content-creating studios of Fox are being tasked with creating content for D+ and Hulu.
Yes, the movies that were on Fox movie studios slate of releases when Disney bought them all bombed, but so does Disney Studios movies that aren't remakes or sequels. Disney certainly hopes to help the now 20th Century Studios to do better. Meanwhile, they kept Searchlight so that Disney can be associated with serious, award-winning films and not just family fare and cartoons.
So, Disney ain't gonna sell off 20th Century since that studio is part of the plan of new content for D+, which is Disney's top priority.
