6. There Might Be A Scene From Age Of Ultron In It
As per
that same Age Of Ultron Q&A that was summarised on Reddit, Feige says that one of his favourite scenes from the Avengers sequel neded up on the cutting room floor because it simply didn't fit the vibe of the film. Apparently that scene will return for Civil War because it was so loved. Could this be a variant of the Hulk scene that
Joss Whedon was quite open about cutting from the last battle of Age Of Ultron? Rumour has it that scene saw Iron Man getting beaten up, only for it to be revealed that Banner was actually inside and Hulks out of it. It would certainly have been a good scene - though Feige's feelings on it would just be guesses at this stage. And obviously there's the small issue of Hulk apparently being completely absent from Civil War after he ran off. But imagine if the fight scene between Black Widow and Hawkeye ends with Hawkeye being attacked by a surprisingly terrible Iron Man, who then Hulks out over Hawk's treatment of Natasha. It would be a glorious pay-off if they're keeping Hulk secret.
