Kevin Feige pitched the Russo Bros. on killing all six original Avengers (not just Iron Man and Black Widow), but the duo refused to do it: "We thought it was way too aggressive and that the audience wouldn’t be able to process it." https://t.co/H6MdeciI6Z— Variety (@Variety) August 5, 2022
The Russo Brothers are admitting that Kevin Feige had a wild idea for Avengers: Endgame -- Killing off all 6 members of the original team.
The Brothers were against the idea because it would have been too agressive and the audience would not have been able to process it all, deciding that one or two characters sacrificing themselves would make a better emotional moment.
Their idea won out in the end with Black Widow and Iron Man dying. Steve Rogers is probably dead too but the MCU has refuses to say whether or not his old ass is still around.
