>IW originally opened with Thanos fucking up Xandar to get the Power Stone, which would set up Richard Rider becoming Nova, but they felt there were too many new characters and Nova wasn't as necessary as the others.
>They briefly considered revealing that Captain America was the Soul Stone in IW.
>The Guardians of the Galaxy would originally only have a brief cameo in IW.
>Scarlet Witch would originally survive in IW, but they felt her EG arc was just "spinning heels" and that it was more impactful to kill her.
>James Gunn was informed about Gamora's death early on and helped write the scene.
>That line about oceanic earthquakes from EG was indeed a Namor reference/setup.
>Original plan for the Time Heist was Tony going to Asgard with Thor to get the Reality Stone and the Space Stone. Tony would be wearing an invisible stealth suit, but Heimdall would be able to see him and they would fight, while fat Thor would fight fit Thor. They scrapped the whole sequence in favor of a more personal scene with Thor and his mom and gave Cap the "fighting your past self" scene.
>Back when Tony was Thor's Time Heist buddy, Rocket was paired with Wanda on a road trip from New York to Washington, D.C. to steal the Mind Stone from the Triskelion.
>Nebula and War Machine's mission originally involved fighting a sea monster in an underwater temple where the Power Stone was hidden.
>They originally planned to show Smart Hulk's Soul World vision, which was a conversation between Banner and Savage Hulk, but there was no time.
>Smart Hulk is not just Banner with Hulk's strength, it's a fusion of their two personalities, which is why he's a bit more cocky than normal Banner.
>Nebula originally used the Infinity Gauntlet and sacrificed herself to wound Thanos, but they axed it because they felt it undermined Tony using it later.
>They considered making Bucky the new Cap, but Falcon made more sense because Cap is all about idealism and Bucky isn't that kind of character.
