So long, studly Grey's Anatomy doctor!

Kevin McKidd (Owen Hunt) is playing a very different character for his new movie North of Hell, and we must admit, we're a bit frightened.

Kevin retweeted a photo of himself from set yesterday (May 23), showing off his down-and-out-looking character. And it looks like we're not the only ones who hardly recognize the Kevster. Earlier in the week, he tweeted, "Gotta say #NorthofHell cast and crew pretty awesome! Be warned, I don't look like myself in this movie - in a bad/good way ;)”

North of Hell is a dark comedy starring Katherine Heigl (Grey's cross-over!), who, according to IMDB, plays the bipolar wife of a businessman (Patrick Wilson).

Stayed tuned for more details on Kevin's role and the dark flick!

Catch the Grey’s Anatomy Season 9 finale on Thursday, May 16, 2013, at 9 p.m. ET/PT on ABC.
