As 'New Moon' fans eagerly count down the days to its November 20 release, Summit Entertainment has just revealed a new behind-the-scenes clip detailing the role of werewolves in the story.

The clip, a combination of actual movie footage and the CGI required to bring it to life, features interviews with Kristen Stewart (Bella Swan), Taylor Lautner (Jacob Black), Chaske Spencer (Sam Uley), and Alex Meraz (Paul) discussing their characters, the interaction between the wolfpack and how the cast and crew drew on the real personalities of wolves to shape their performances.
