Holy Pancakes again!  Kate Beckinsale's posterior is prominently featured in the ads for the new Underworld movie.  This time, we get so see her crawling through a heating duct in a skin tight catsuit.  Oh, and she fights a giant werewolf and stuff too.  More after the jump.

Yeah, I got the "booty screen cap", but watch the clips and if you don't think Kate's "smokin' hot bod" is a featured player in this movie than you're crazy. This woman is jaw-droppingly-beautiful and groan-inducing hot.  She turns boys into men with just one look. And lets not forget she has that gorgeous English accent to go along with the bod.  Num!
