Stranger Things star Finn Wolfhard recently wrapped filming his directorial debut, a slasher comedy called Hell of a Summer, up in Canada with Billy Bryk of Winona Earp.

"Every day on set we'd just start laughing," Wolfhard tells EW in an interview for PlayStation Players, a celebrity program he joined at Sony. "'Oh my God, they gave money to two kids to make a crazy [movie].' Not to downplay it, I'm incredibly proud of it, but it was a crazy thing."

The actor, 20, recalls having to drum up financing to make the movie and how often potential investors would remark on his age. "That's what everyone said when we tried to get money for this movie. They're like, 'You're a little young to be directing a movie,'" he says. "I'm like, 'Yep.'"
