Luigi Actor Charlie Day Has Begun Recording Mario Movie But Admits, “I Know Nothing”

Actor Charlie Day is voicing Luigi in the upcoming Super Mario movie, and now the It’s Always Sunny star has shared as much information about the film as he can–and it’s not very much. Appearing on Jimmy Kimmel Live, Day he’s forbidden to discuss specifics, joking that Universal and Nintendo would hurt him physically if he divulged any secrets.

“I’d love to tell you all about it, but they are top secret with this stuff. Absolutely, this is serious stuff,” Day said.

Day has begun recording his lines for the Mario movie, but he hasn’t seen the script and acknowledges that he doesn’t know anything about the story. “I know nothing. I show up, and they’re like, ‘You say this and you say that.’ And it’s all very funny and good. And then I walk out and there’s like two guys in overalls with hammers that are like, ‘Don’t you tell nobody nothing about this, Charlie. I swear to God we’re gonna get your kneecaps, we’re gonna break your neck.'”
