Avengers: Infinity War - 12 Behind-The-Scenes Secrets You Need To Know

4. Bruce Banner Fights A "Hulk"

Another set leak photo from the New York sequence immediately after Bruce Banner lands on Earth after encountering Thanos with Thor offered an intriguing hint. That image showed Mark Ruffalo battling a CG-character with giant Hulk-like hands, which prompted some to speculate that Banner was going to fight Hulk (or a projection of Hulk).

That would be an insane decision, though a rather fitting one, but it's more likely that this was in fact a reveal that Banner, Iron Man, Wong and Doctor Strange fight Thanos' Hulk - Black Dwarf (or Cull Obsidian to give him his speculated alternative name).

Given Banner's arc will apparently include more of his fears that he'll lose control to the Hulk, having him put under such a threat that Hulk would be able to deal with would make a lot of sense. But it's almost more interesting to think of him playing out that battle in real terms (somehow using Ebony Maw's powers of manipulation, perhaps?)
