“I love Carey. Listen, it’s stuff she does in a movie, there’s no way I could do it. There’s no way I could. I just watch her and I say, ‘Well, that is just the next level of acting,’” gushes Sandler.

“I was just trying to make sure I stayed out of the way for Carey. She’s amazing. It’s so real. It’s so effortless,” he continues.

Mulligan is a fan of Sandler’s work as well. “I am such an enormous fan,” thePromising Young Womanstar recently said in an interview with Netflix. “In fact, before we shot, I watched all of his movies.”

But Sandler tells PEOPLE that’s not quite true. “She only watched like six,” he quips. “She started all of them. Turned a lot of them off.”

Her two favorites? The 1998 comedyThe Waterboyand the 2023 animatedLeo, which also features the voices of Sander’s daughters.

“She lovesLeo. You wouldn’t think she would loveLeobecause she’s a grown lady, but she locked in withLeo,” says Sandler.

Mulligan says she’s also partial to the 2017 dramedyThe Meyerowitz Stories, costarringBen StillerandDustin Hoffman.

“I think you love it because you thought I was Stiller in it,” Sandler jokes.

“I thought you were Stiller. I love Stiller,” Mulligan responds.

“She loves Stiller and somehow that benefited me,” Sandler replies.

Sandler has previously opened up about giving his daughters career advice. “I tell them to make sure you feel good about what you do and how hard you worked, and you judge yourself,” he PEOPLE last year at theLeopremiere.

“Don’t let too many people try to get in your head. If you feel like you gave it your all, that’s all you can ask,” he continued.
