Timothée Chalamet’s emotions were out of this world on his 30th birthday. 

After all, his girlfriend Kylie Jenner surprised him with a private screening of his 2014 film Interstellar last December. But while the Dune actor was ultimately grateful for this gift, he shared he wasn’t in the greatest mood leading up to the celebration. 

“I was grumpy on the way there because I didn’t know where she was taking me,” Timothée reflected to his Interstellar costar Matthew McConaughey in a clip shared on Jan. 20 of their upcoming conversation for CNN. “Like, ‘It’s my birthday. Why are we driving 30 minutes outside of L.A.?’”

However, all that changed when he realized the surprise she’d planned for him. As he recalled, “I got to the theater and it was Interstellar in IMAX. I said, ‘Oh, I’m sorry for being so grumpy on the drive.’ I love that movie, man.”

Indeed, he’s always had a soft spot for the film (in which he portrayed Tom Cooper, the son of Matthew’s character Joseph Cooper) since its release over a decade ago.
