Emile Zola: I don't eat meat.
Col. Phillips: Why not?
Zola: It disagrees with me.
Phillips: How about cyanide? Does that give you the rumbly-tummy too?
US Army soldier: Wait! You know what you're doing?
Steve Rogers: Yeah, I've knocked out Adolf Hitler over 200 times.
Steve Rogers: I thought you were dead.

Steve Rogers: I know this neighborhood. I got beat up in that alley. And that parking lot. And behind that diner.
Abraham Erskine: Do you want to kill Nazis?
Steve Rogers: Is this a test?
Abraham Erskine: Yes.
Steve Rogers: I don't want to kill anyone. I don't like bullies; I don't care where they're from.
Abraham Erskine: Whatever happens tomorrow you must promise me one thing. That you will stay who you are. Not a perfect soldier, but a good man.
Steve Rogers: That wasn't so bad...
Abraham Erskine: That was the penicillin.
Peggy Carter: How do you feel?
Steve Rogers: Taller.
Steve Rogers: Who the hell are you?

Howard Stark: I'd love to stay and talk, but I have to be in New Mexico by morning.
Steve Rogers: What's in New Mexico?
Howard Stark: The Rio Grande. Billy the Kid's resting place. Los Almos. This and that, you know.
Abraham Erskine: Why someone weak? Because a weak man knows the value of strength, the value of power.
Steve Rogers: I know you don't think I can do this...

Col. Chester Phillips: General Patton has said that wars are fought with weapons but are won by men. Our goal is to create the greatest army in history. But every army begins with one man. He will be the first in a new breed of super-soldier. We are going to win this war because we have the best men. And they, personally, will escort Adolf Hitler to the gates of Hell.
Chosen answer: A couple of techniques were used. In most cases, Evans would film the scene normally, then the effects team would digitally shrink his character down to the smaller size. This would generally require some on-set adjustment to allow for eyelines - in some cases Evans would be physically lower than other actors, in others, they would look at his upper chest while he looked over their heads. In a few cases, actor Leander Deeny, who possessed the necessary scrawny physique, would film the scene, collaborating closely with Evans to ensure that the character's mannerisms remained the same. Deeny's features would then be digitally replaced with those of Chris Evans. Deeny appears briefly in the movie as the bartender in the pub Rogers visits to recruit his team.
