Marketing ideas for a small, independent movie theater?

I work at a small, single screen, independent movie theater. We get mostly big, first run movies, but I'm trying to think of some ideas for marketing. So far I've thought of a few things such as playing a Christmas movie every Monday night in December (Monday nights are generally our slowest time of the week and we usually lose money) and giving out free hot coco or apple cider or something. Another idea I had was hosting a Super Bowl party, showing the game on the big screen and having it catered by a local sports bar down the street with whom we've done advertising with in the past. I'm open to any suggestions. Thanks a lot!
