Avengers: Infinity War writers Stephen McFeely and Christopher Markus revealed one deleted scene in Infinity War which went too far. It involved the bloody mashed potatoes.
Markus and McFeely were asked if there were any moments when writing Infinity War or Endgame and presenting it to the producers and Kevin Feige, they considered it is “going too far?”
“There was one scene, it was in Infinity War,” Markus started. “We wrote it we didn’t shoot it. It was part and parcel of a whole thing where we realized we were picking up the characters too early in their arc before Thanos had gotten to them. It was a scene of basically Widow and Falcom and Cap in hiding post-Civil War and they’d just been through a big fight with criminals, and Cap was eating mashed potatoes, and Falcon says “You’re bleeding into your mashed potatoes.” He looks at him like… yeah he is bleeding into his mashed potatoes. I remember Kevin [Feige] going “He’s bleeding into his mashed potatoes?! I don’t want to see that!” Yeah, maybe we went a little too…something.”
From both Infinity War and Endgame, this story was just one of the many scenes and stories cut. The Living Tribunal, The Birth of Smart Hulk, Captain America and Red Skull teaming up. Also, Thanos killing the past Avengers included.
What did make it into Avengers: Infinity War, however, earned it the number 5 spot in a ranking of the Marvel Cinematic Universe’s Infinity Saga.
