Are all marvel characters owned by Disney?

Until the contract with Universal expires, it’s unlikely we will see a solo Hulk film in the MCU.

I actually enjoyed the Incredible Hulk film from 2008. Thought it was a good follow up to Iron Man. What I meant to say is that we shouldn’t expect another solo Hulk film in the MCU, ie. with Mark Ruffalo as the title character. After all the behind the scenes drama that happened with Edward Norton, it’s no surprise that Universal are digging their heels in and preventing another Hulk film from happening.

Spider-Man is owned by Sony but he appears in the MCU films through a property-sharing deal between Sony and Marvel Studios (owned by Disney). Sony finance the MCU Spider-Man movies and take a majority share of the profits while Marvel have creative control and merchandising rights.

Creative rights to Hulk belong to Marvel but distribution rights are with Universal Studios. The contract states that should Marvel make any film with Hulk in the title and/or as the main character, Universal get first right of refusal on distribution. Hence why Hulk has only appeared as an ensemble character in Avengers films and Thor Ragnarok. Until the contract with Universal expires, it’s unlikely we will see a solo Hulk film in the MCU. The relationship between Marvel and Universal went sour after the Incredible Hulk film from 2008 flopped.

X-Men, Deadpool and Fantastic Four were formerly owned by 20th Century Fox. And since the Fox movie division was merged with Disney after their $71 billion dollar acquisition closed earlier this year, all these properties are expected to become part of the MCU in the near future. Don’t expect new films any time soon though - Kevin Feige himself estimates another 5-10 years until we will see the X-Men join forces with the Avengers.
