The writers of Avengers: Endgame almost included a scene where Hulk and Bruce Banner talked to each other.
Co-writer Christopher Markus told Cinema Blend that the scene would’ve taken place after Hulk snaps his fingers wearing the Infinity Gauntlet and brings everybody back. In Avengers: Infinity War, Thanos sees a young Gamora after he snaps his fingers. So, the writers imagined what Bruce Banner would’ve seen.
“We did actually write a version, and this existed before The Ancient One scene was slowly beaten out, but there was a version where it was Banner talking to The Hulk… and we never shot it, but it was kind of a cool thing to get them both on screen together interacting,” Markus said.
