From Thanksgiving until New Years Day, Trylon Discount Cards come with a free popcorn. Butter too, if you want.
Legal mumbo jumbo: Discount cards do not expire and are valid at any screening listed on this website, including shows at the Heights and Riverview, unless otherwise noted in the screening description. Screenings with live music have a $4 surcharge. This policy is retroactive, and includes older cards with expiration dates indicated on the reverse. If you find one from 2009, use it!
