Besides having a drawing for a gold pass, a lot of people would really enjoy getting an "Exclusive Behind the Scenes Tour" of your theater. Offer the drawing winner and a friend free admission to a movie of their choice and have them come early, show them the projection booth, and talk to them about how everything runs. They are sure to have questions. At the end, let them scoop their own popcorn, fill their own drinks, grab a box of candy (all free of course), put it all in their seats (let them in early before the crowd so they can get the best middle seats) and finally, "throw the switch" on the projector that is showing their movie and give them each a hat/shirt/mug with the theater's name or logo on it. I'd sign up!
