Scream 4 co-stars David Arquette, Neve Campbell and Emma Roberts (plus director Wes Craven) attended Saturday's 2010 Spike TV Scream Awards at L.A.'s Greek Theatre.

Noticeably absent was wife and co-star Courteney Cox. She and David met on the set of the original Scream in 1996 and later married on June 12, 1999.

The cast was on hand to premiere new footage from the upcoming horror flick, but the evening truly belonged to old school sci-fi stars...

Dressed up in his Ghostbusters gear, Bill Murray showed up to accept the awards for Best Horror Movie for Zombieland while Alien star Sigourney Weaver was awarded Best Heroine. And lastly, Michael J. Fox and Christopher Lloyd were awarded the 25th Anniversary Award for Back to the Future and hugged each other in front of the DeLorean. Aww!

Kristen Stewart also put in an appearance, winning for Best Actress in a Fantasy (Eclipse) and took home the awards for Ultimate Scream and Best Fantasy Movie.

See the other major award winners below the cut! The show airs this Tuesday at 9pm on Spike TV.
