Tomorrow night at 9pm ET/PT, MTV airs its first-ever Halloween special, "Ulalume: Howling at New Moon." As you might imagine, the November 20 release of "New Moon" will be getting a lot of attention during the special. Expect cast members to pop up throughout the hour-long television event.

Of course, the highlight for many of you will come when "Twilight" stars Robert Pattinson, Kristen Stewart and Taylor Lautner step into the spotlight to debut a brand new clip from "New Moon." And since the clip is already in-house and being processed for your viewing pleasure, we couldn't help but grab a couple stills to share with you here on MTV.com.

EDIT: Have some more.
