'Grimm': David Giuntoli and Russell Hornsby talk double lives and rats

NBC is bringing the creepy factor on its Friday night fairy tale show "Grimm." But the program is more than meets the eye. It has a complex back story for its main character Nick Burkhardt (David Giuntoli) who is constantly fending off his foes while keeping secrets from friends, including fellow cop Hank Griffin (Russell Hornsby).

The stars of the show, Giuntoli and Hornsby, sat down with Zap2it to talk about a variety of subjects. Here are a few highlights:

On how Burkhardt will keep his identity a secret: "As the show goes on, I realize that the bad boys are coming for me where ever I am...It's getting dangerously close to everybody...I'm spinning a lot of plates. I'm trying to figure out how to live a double life."

On Hornsby's favorite Grimm tale: "I enjoy 'The Pied Piper' because I'm deathly afraid of rats. And it's like one of those things where what you're afraid of, you're attracted to."

On Burkhardt's relationship with Monroe: "It's always a tentative relationship with Monroe. I think he'll bite me and I think he'll help me. But which one we're going to get, we don't know."

On how Burkhardt will fend off his foes: "Eventually I'm going to have to start working some of these people: politically, strong arming them, making them stay away from my friends, working with them and making alliances."

The show airs at 9 p.m. ET on Fridays.
