I was searching for Fox's agreement with Universal on theme park rights for the Simpsons and may have bumped into the Marvel Paramount contract, which according to Marvel is pretty much the same terms as the Marvel Universal contract. And as usually happens with me when I find such things I go down the rabbit hole lol. I haven't read it like I did the Spider-Man one, but I can tell you that Marvel got MUCH smarter than they were in the 90s. It also confirms what we had figured out because of those ABC planned Hulk TV shows. The only rights that Marvel does not have is the distribution rights to the movies.
It seems to me that the distribution rights that Universal has on Hulk has an expiration date of 15 years + 3 pay TV windows. It would also help explain why Disney hasn't tried to acquire those rights since they weren't as imperative to own to kick off the MCU as the Paramount contract was. Marvel and Paramount amended the 2005 contract in 2008 which meant they had the rights to Avengers, Iron Man, Thor, Cap and sequels. Disney HAD to acquire those from Paramount. Hulk could wait, especially if there's an expiration date on the distribution rights.
Paramount extends deal with Marvel
Anyways, be warned. This may be a confusing post. I have spent the past few hours going down this rabbit hole. I may be wrong. Hell I must likely am, so anyone can check the links here and try to figure it out.
