Nothing screams Merry Christmas! like a slasher film. Horror queen Jill Sixx (with an assist from Critical Mass Releasing and the Grindhouse Film Festival) hosts a 7:30 p.m. screening of 1974's Black Christmas at Screenland Armour (408 Armour Road, North Kansas City, 816-421-9700). "Many consider this to be the first slasher film," Sixx says of the flick in which sorority girls die. Get scared and give back — proceeds from the $5 admission fee go to sCare (Suspense Community Allocating Relief and Empowerment) Foundation, a Los Angeles nonprofit that supports at-risk youth (scarefoundation.org). Enter the raffle for prizes to then gift your creepy friends. Buy tickets and get more information at screenland.com/armour.
