The "Call Me By Your Name" star played the younger version of Tom, the son of Matthew McConaughey's Cooper.
"When I did Interstellar, I saw it 12 times in theatres in IMAX... Christopher Nolan held a screening at Lincoln Square. I forgot about this. I really haven't thought about this moment until right now. It was surreal because it's a huge IMAX theater and I really had no career at this point, so I was like the fraud a little bit in the room," the actor said.
"I saw it, and I loved it, but I went home to my dad and wept for an hour because I just figured my part was bigger. They didn't even cut anything. I just figuredI don't know what I figured," he added.
Chalamet also said that he filmed a long monologue for the film which was not cut, but McCaughney's face was displayed on screen for most of the part.
