In Avengers: Endgame, characters poked fun at previous time travel movies, pointing out why its version of the concept was nothing like such films as Back to the Future. However, there was another movie mentioned, and it was one Sebastian Stan has a special connection to: Hot Tub Time Machine.

Stan starred in Hot Tub Time Machine as Blaine, making many wonder how that might affect the actor also playing Winter Soldier. Stan addressed the paradox, and what might happen if Winter Soldier and the Hot Tub Time Machine actor met, at Jus In Bello in Italy, saying, "An interesting predicament. It would probably be, like, his worst nightmare or something, I don't know. I remember I was watching the movie and they made that reference and I kinda looked around excitedly, but no one cared. I was the only one that really cared."
