Avengers 4: Every Character Confirmed So Far
12. The Hulk
Confirmed By: Mark Ruffalo
It's still something of a travesty that we've not seen a solo Hulk movie since the REAL dawn of the MCU made him a good character again, but at least Thor: Ragnarok will at least partly address that by adapting some of Planet Hulk.
Mark Ruffalo confirmed he's appearing in Avengers 4 before set photos doubly did so:
"There's a huge change for Banner and for Hulk. It isn't resolved in the first Infinity War, it sort of culminates into the second Infinity War. Thor 3 is the beginning of a lot of changes for Banner and for Hulk."
And his sruvival at the end of Infinity War proved as much too.
