As Gossip Girl's Dan Humphrey, Penn Badgley may have to deal with dating drama and long-lost relatives showing up... but he's going through a whole different kind of drama this weekend in the horror flick, The Stepfather, in theaters now!

Penn plays a guy who returns home from military school to discover that his mom's new husband is now living with them -- and that there's a mysterious side to his stepfather that his mom doesn't see.

But it's not the kind of scary movie you'd expect. "There's less eerie, creepy, bloody stuff and more relatability in the sense that's it's a slower, simpler movie that draws you in," Penn says.

But the best part? Tons of shirtless scenes with Penn! "I got to do a lot of my own stunts and do some fight sequences and that kind of stuff and I think that hopefully people will take it in stride and believe it," he says. "I think I was believable and, I mean, it was really fun for me. I took to it like a fish in water, which is a terrible analogy to make 'cause I'm in the water the entire time, shirtless."

Will you see The Stepfather this weekend?
