Avengers: Endgame - 10 Secrets We Just Learned From The Writers At Comic-Con
3. The Tony & Howard Scene Was Inspired By Markus' Personal Life
One of Endgame's emotional highlights is the touching conversation between Tony and Howard Stark. Writers often draw from their own personal experiences when building scenes and characters, even for fantasy and sci-fi stories, and with Endgame, this was one such moment.
In Civil War, we learn that Tony never got to (properly) say goodbye to his father before he was killed by The Winter Soldier, which led to Tony creating BARF, so he could relive their final moments together over and over again. But in Endgame, Tony finally gets some real closure with his old man.
In recent years, Markus' father passed away, and he also had a child. So, while writing Endgame, the whole parenting conversation between Howard and Tony came straight from Markus' desire to share that nervousness and self doubt people can feel before welcoming a baby into the world.
