So where does the Incredible Hulk go from Ragnarok?
The success of Marvel Studios' not so jolly, green and gamma-radiated giant in Thor: Ragnarok - as well as his guest appearances in past and future Avengers films - has proven the Hulk still has potential on the big screen.
What isn't so clear is if the Hulk will continue to be the strongest guest star there is, or if he'll once again star in his own movie as he did back in the early days of Marvel Studios. Mark Ruffalo - the only actor who has played Bruce Banner/Hulk in multiple movies - said in July that a Hulk movie would never happen because Universal doesn't want to play nice with Marvel Studios. If Marvel Studios wants to use the green giant in a movie, it must be in a guest star/team-up way; if they wanted to make a solo effort, Universal would have to be involved.
Marvel Studios has proven they can share with others with their successful reboot of Spider-Man. During the early days of the Marvel Cinematic Universe, no one thought Spider-Man would be able to take part in an Avengers movie because the web-slinger's rights belonged to Sony. But Marvel Studios made a bold move to collaborate, and Sony wisely realised they were in danger of tarnishing a once indestructible superhero movie brand. Both sides made it work.
