During a recent virtual watch party for Avengers: Endgame, Robert Downey Jr. popped in to say hello, during the reconciliation scene between Cap and Iron Man, and explained the significance of the scene for the story and the characters.
The scene Robert Downey Jr. is speaking of takes place in the middle of the second act of the movie, when Tony comes to the Avengers with his plan to use time travel to fight Thanos.
As Downey Jr. explains, it was not just about the two deciding to reconcile.
It was moments of emotional resonance such as these that made Avengers: Endgame a fitting end to the Infinity Saga and not just another mindless action blockbuster.
