Avengers: Endgame (2019)
Tony Stark: When I drift off, I will dream about you. It's always you.
Steve Rogers: We lost. All of us. We lost friends. We lost family. We lost a part of ourselves. This is the fight of our lives.
Natasha Romanoff: This is gonna work, Steve.
Steve Rogers: I know it is. 'Cause I don't know what I'm gonna do if it doesn't.
[from trailer, Tony records message from space through his broken helmet]
Tony Stark: This thing on?... Hey Ms. Potts. If you find this recording, don't feel bad about this. Part of the journey is the end. Just for the record, being adrift in space with zero promise of rescue is more fun than it sounds. Food and water ran out four days ago. Oxygen will run out tomorrow morning. And that'll be it. When I drift off, I will dream about you. It's always you.

[from trailer, Steve and Nat see Scott Lang, alone at the entrance of the Avengers HQ through a security camera]
Scott Lang: Hi! Uh, is anyone home? This is Scott Lang. We met a few years ago, at the airport, in Germany? I got really big.
Steve Rogers: Is this an old message?
Scott Lang: Ant-Man? Ant-M - I know you know wh - I know you know that!
Natasha Romanoff: That's the front door.
Scott Lang: That's me. Can you buzz me in?
