Captain America: The Winter Soldier Audio Commentary:

“We always said that the whole movie lives or dies on that last scene between him and Bucky. It’s a superhero movie, the expectation is that he will win. But the real story is will he win Bucky? Will he save his friend? Will his friend kill him? Will he have to kill his friend? The tragedy of that moment was the most important thing to us as directors in the third act. That’s the real climax of the act.
The whole film comes down to this minute and a half. Steve is trying to save his past. It’s the last thing he has left, really.”
