In an unprecedented crossover event within the Marvel Cinematic Universe, Mark Ruffalo and Edward Norton return as two distinct versions of Bruce Banner in Hulk: World War — a sci-fi action epic where rage collides with redemption across the multiverse. After a catastrophic nuclear experiment tears open a rift between dimensions, Bruce Banner (Mark Ruffalo) is pulled into a parallel universe where another version of himself (Edward Norton) never gained control over his inner monster. This alternate Hulk has evolved into a feral warlord, ruling the planet Sakaar with unchecked fury and destruction. As the threat of multiversal collapse looms, the two Banners must face off in a battle that pits reason against rage, and past against present. Both men carry scars—emotional, physical, and cosmic—but only one can prevent total annihilation. Blending the emotional depth of Marvel’s most tormented hero with explosive action inspired by the iconic World War Hulk comic arc, Hulk: World War is a stunning, character-driven spectacle where the biggest fight… is the one within.
