Avengers: Endgame - 10 Secrets We Just Learned From The Writers At Comic-Con
1. Thanos Almost Chopped Off Cap's Head
Endgame isn't sunshine and rainbows from start to end, but it's also not unbearably dark, either. However, if one of Markus and McFeely's early ideas had made the final cut, the scales would've tipped much more heavily towards the sinister end of the tonal spectrum.
As crazy as it sounds, the writers once considered including a scene where 2014 Thanos entered the final battle by throwing down the severed head of 2012 Captain America, showing the Avengers that he had utterly devastated that other reality and was capable of doing the same to theirs.
For obvious reasons, this idea was nipped in the bud early on, and the final version of Endgame only features a single decapitated head.
