As for whether Louis-Dreyfus' cancer diagnosis could become a storyline for her Veep character, Selina Meyer, Hale said he wasn't sure.
"I'm always surprised by what these writers come up with," he said.
While Louis-Dreyfus focuses on her recovery, Hale is celebrating the release of his latest movie, telling ET why Love, Simon is a film that all kids and parents should see.
"I just love that it’s this kid’s unique story. He’s never had a chance to be honest about his sexuality and it’s his chance to [open up]," he expressed. "There’s just a lot of kids out there that I think feel very isolated, and this gives them permission to be honest and feel supported, and I love that."
