For $25, Cinemark is offering moviegoers a "festival pass," which includes a collectible key chain, a special cup that can be refilled for $3.50 through the end of 2018, and a commemorative festival badge. Your kids can display their badges in their rooms proudly, the same way I display my (now-laminated) bookmark from when I picked up my copy of The Goblet of Fire on July 8, 2000.
