Nick Fury (about Hulk): Probably jumped out and swam to Fiji. He'll send a postcard.
Natasha Romanoff: "Wish you were here." You sent me to recruit him way back when. Did you know then what was gonna happen?
Nick Fury: You never know. You hope for the best, then make do with what you get. I got a great team.
Natasha Romanoff: Nothing lasts forever.
Nick Fury: Trouble, Ms. Romanoff. No matter who wins or loses, trouble still comes around.
Tony Stark: Romanoff. You and Banner better not be playing "hide the zucchini."
Natasha Romanoff: Relax, shellhead. Not all of us can fly. What's the drill?
Tony Stark: This is the drill. If Ultron gets a hand on the core, we lose.
Thor: Is that the best you can do?
(Ultron calls in his androids)
Steve Rogers: You had to ask.
Ultron: This is the best I can do. This is exactly what I wanted. All of you against all of me. How can you possibly hope to stop me?
Tony Stark: Well, like the old man said... (looks at Steve) together.
Natasha Romanoff: Cap, these people are going nowhere. If Stark finds a way to blow this rock...
Steve Rogers: Not till everyone's safe.
Natasha Romanoff: Everyone up here versus everyone down there? There's no math there.
Steve Rogers: I'm not leaving this rock with one civilian on it.
Natasha Romanoff: I didn't say we should leave. There's worse ways to go. Where else am I gonna get a view like this?
Natasha Romanoff: How's little Natasha?
Laura Barton: She's... Nathaniel.
Natasha Romanoff: Traitor.
Natasha Romanoff: Thanos did exactly what he said he was going to do. He wiped out fifty percent of all living creatures.
Natasha Romanoff: Just like Budapest all over again.
Clint Barton: You and I remember Budapest very differently.
Clint Barton: Why am I back? How did you get him out?
Natasha Romanoff: Cognitive recalibration. I hit you really hard on the head.
Clint Barton: Thanks.
Clint Barton: Have you ever had someone take your brain and play? Pull you out and stuff something else in? Do you know what it's like to be unmade?
Natasha Romanoff: You know that I do.
As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality. Everything the Avengers have fought for has led up to this moment - the fate of Earth and existence itself has never been more uncertain. (IMDb) │ Produced by Marvel
