Avengers: Endgame continues to plow its way through any and all box office records, currently on the verge of seizing Avatar's blue-tinted crown. Now, coming off an extensive and well-received Reddit AMA, Marvel Studios President Kevin Feige gave fans many tidbits to unpack concerning his vision, work ethic, and history shaping the Marvel Cinematic Universe. One interesting tidbit arose when Feige reflected one the road thus far, revealing the one, perhaps slightly unexpected scene that kept the story moving on its forward trajectory.

"I will say my entire MCU career was building up to that ‘on your left’ moment in Endgame," writes Feige, alluding to a moment during the climactic Endgame battle, in which Falcon flies through to add his muscle to the cause. He also reveals his biggest regret, innocuous though it may be. "I made a joke once about regretting dying Chris Hemsworth eyebrows blonde for the first Thor, but the truth is it's everything in those films and all the little details: the perfect ones and not so perfect ones, that carried us through to the experience of Endgame. Therefore, I wouldn't change a thing.

Feige also reveals the formative steps in bringing the Infinity Gauntlet saga to life, revealing that preliminary discussions transpired relatively early on in the game. "We started discussing how to adapt the Infinity Gauntlet comic soon after the release of the first Avengers," he explains. "It was on one of our creative retreats about 5 years ago that we decided to do it as two films. We started to crack the specifics of the story during production on Civil War with Chris Markus and Stephen McFeely, Joe and Anthony Russo, in a conference room as we went back and forth between takes."
