Mark Ruffalo's The Hulk will return in Thor: Ragnarok, and it looks like he will be fighting the God of Thunder before teaming up.
Chris Hemsworth shared a video in Instagram of himself working out and punching a heavy bag.
"Gettin ready to fight the Hulk," Hemsworth said.
The clip shows the Thor: Ragnarok star jabbing and punching at the bag, which probably represents Hulk's head. The upcoming Marvel film will feature Thor and Hulk meeting in the gladiator arena, but specific details haven't been revealed about the scene. We'll probably see both Avengers brawl against each other before teaming up to escape. What do you think will happen?
Directed by Taika Waititi, the film stars Chris Hemsworth as Thor, Mark Ruffalo as Hulk/Banner, Tom Hiddleston as Loki, Idris Elba as Heimdall, Cate Blanchett as Hela, Tessa Thompson as Valkyrie, Jeff Goldblum as Grandmaster, Anthony Hopkins as Odin and Sam Neill in an unknown role.
Thor: Ragnarok will hit theaters on November 3, 2017.
