Univeral Pictures has the distribution rights to the
Hulk franchise, which include characters like Bruce Banner/Hulk, Betty Ross, General Ross, Abomination, She-Hulk, and the Leader. Marvel can utilize these characters to a degree in other projects, but any movie with these characters squarely in the lead role would have to be done in partnership with Universal - and players involved say that isn't going to happen.
"I wanna make just one thing perfectly clear today, a standalone Hulk movie will never happen," Mark Ruffalo told
Variety in July 2017. "For some reason [Universal doesn't] know how to play well with Marvel... because they don't want to make money."
2008's
Incredible Hulk film was made in a partnership by Universal and Marvel Studios, but the two sides have been unable to come to terms on anything similiar since the success of 2008's
Iron Man.
In a similiar situation, the rights to Marvel Comics' earliest character Namor are also tied up in rights situations. Marvel Studios' president Kevin Feige previously said that any
Namor film would have to include Marvel Studios but that the film rights are owned by other parties including Universal (which optioned the character in 2001).
"Let’s put it this way - there are entanglements that make it less easy. There are older contracts that still involve other parties that mean we need to work things out before we move forward on it," Feige told
IGN. "As opposed to an Iron Man or any of the Avengers or any of the other Marvel characters where we could just put them in."
