David Giuntoli

If reality dating shows and sunburn aren't enough danger for you this summer, catch up on NBC's Grimm.

In the hit supernatural procedural, Portland cop Nick (David Giuntoli) discovers he's descended from a long line of Grimms, people who can recognize the literal fairy-tale beasts inside of everyday people. Yes, the Big Bad Wolf is real. No, he may not really be bad anymore. In fact, his name is Monroe, and he loves to play the cello!
