I went to the midnight showing and we are an hour in to the movie when the projector cuts off and no movie. Some guys down front start doing shadow puppets. And then the light came back on, but no one came in to explain what was going on.
Then a few minutes later the movie started up again, then stopped, then started, then stopped. This went on for a few minutes than finally the movie started again. And we finished it and just as it's the last show and it's about to go to credit it shut off again. It came back on in time to see the little bonus clips.
It was actually pretty funny towards the end, but all part of the midnight showing experience.
