The other day, I walked into the local theater to watch a showing of Captain Phillips. As I approached the door to Auditorium 4, popcorn and Pepsi in hand, I could hear the trailers still running, complete with epic music and bass-heavy vocals. Whatever was playing sounded pretty good, so I elbowed through the door and stared up at the screen. Except nothing was up there. The screen was blank; the room was pitch black. The audio kept playing, but somebody had glitched the visuals.
