Can't think of the name of this movie?!

Can't think of the name of this movie?

I'm going to start off by saying the description is going to be very vague so I'll apologize for that.

I remember seeing a trailer for some movie on AOTS, Attack of The Show, a few months ago and I THINK it was about vampires or some other mystical creature. All I can clearly remember from the trailer was someone was running on the side of a building or something and it seemed to be a lot of action. I'm so sorry that I can't add more, but I was trying to think of the name, but I just couldn't.

If you know the movie I'm talking about then I thank you so very much.

I know they showed a trailer on aots for the vampire movie 30 Days of Night. Or it could be Skinwalkers.
