According to Jennifer Lawrence, Timothée Chalamet was constantly cracking people up on set while filming scenes with them, especially her and Leonardo DiCaprio. "Timothée gave us all so much comedic relief," Lawrence explained. "He was improving and was just killing Leo." Lawrence's character Kate in "Don't Look Up" meets Chalamet's Yule inside a supermarket where she works, and later forms a bond with him. The two spend the majority of Chalamet's screen time together, with DiCaprio eventually joining them.
"I had a scene [where] I started on the outside and I had to walk back in the room, so I had to wait until they called cut, but I just saw Leo's face — he wasn't on camera — but his face was just bright red, he like couldn't breathe," Lawrence recalled. "He was holding in a laugh and I had to wait until cut to be like, 'What [Chalamet] say?'" Laughing, DiCaprio added, "He would say the most random stuff, it was incredible."
The fact that Chalamet was able to get one over DiCaprio like that is a pretty impressive achievement, considering that DiCaprio himself is a known on-set joker. In fact, as a direct result of his various pranks, he and Claire Danes couldn't stand each other in real life despite playing lovers in Baz Luhrmann's "Romeo + Juliet."
