Avengers: Age Of Ultron Ending - 14 Implications For Phase 3 And Beyond
11. Could There Now Be A Hulk Movie?
There are now two possibilities for how Marvel will deal with the big green monster. Less spectacularly of the two, they could merely say he's gone off the grid to hide from the consequences of his rampage, and thus deflect negative attention from the Avengers.
That would mean he wouldn't be involved in Infinity Wars - or at least the start of it - and will turn up in his own stand-alone in Phase 4.
The other possibility is that Marvel do what fans have wanted (perhaps foolishly) for a long time, and announce a stand-alone that runs concurrently with Phase 3 (and is more like a spin-off of the main Avengers thread). If they choose to take Banner's worries about not having anywhere "in the world" where he's not a threat, that might mean he exiles himself in space.
While that wouldn't quite fit with the traditional approach to Planet Hulk, it could open that possibility, but far more compelling is for him to become entwined with the Guardians Of The Galaxy or the Inhumans. Which might not actually lead to a solo project, but a more expanded supporting role.
