Cult Movie Party
Some of the best cult movies are Halloween-themed. Ask your guests to come dressed as their favorite character from whatever movie you decide to screen during your party - "The Nightmare Before Christmas," "It's the Great Pumpkin, Charlie Brown," and "Friday the 13th" are classic choices. Or choose something a from the cult archives, such as "Plan 9 from Outer Space" or "The Rocky Horror Picture Show."
Put together a playlist of party music from classic Halloween-y films; think songs like Ghostbusters (from "Ghostbusters"), Weird Science (from "Weird Science") and Time Warp (from "The Rocky Horror Picture Show") to get people in a frightfully festive mood before and after the flicks.
