What would an awards show that honors all things sci-fi, fantasy, comics and horror be without one killer exclusive? This year's Scream Awards will feature an exclusive clip from one of the most highly anticipated films set for release this fall.

MTV News can exclusively announce that the show, which airs October 19 on Spike, will feature a world premiere sneak peek at "Harry Potter and the Deathly Hallows, Part 1." And that sneak peek will include some never-before-seen footage.

Also, fans who are gearing up for the release of "Green Lantern" will be happy to hear that both its leading man, Ryan Reynolds, and leading lady, Blake Lively, will be attending the celeb-filled Scream Awards show. And they won't be the only A-listers on hand that night. Other celebrities expected to appear include Kristen Stewart; recently separated David Arquette, Emma Roberts, Neve Campbell and director Wes Craven from "Scream 4"; Megan Fox; Sigourney Weaver; Christopher Nolan; and Nina Dobrev, Paul Wesley and Ian Somerhalder from "The Vampire Diaries."

Nominees for the night include "The Crazies," "Paranormal Activity," "Shutter Island," "Thirst" and "Zombieland" for Best Horror Movie; "Dexter," "Doctor Who," "Lost," "True Blood" and "V" for Best TV Show; and the casts of "Inception," "Iron Man 2," "Kick-Ass," "Lost," "True Blood" and "Zombieland" for Best Ensemble.

The Scream Awards will also pay their final respects to "Lost" with a farewell tribute that will feature the show's stars Jorge Garcia, Harold Perrineau and Henry Ian Cusick and the show's writers/producers Carlton Cuse and Damon Lindelof.

M.I.A. is scheduled to perform at the show.
