Before they show audiences the feature presentation in a movie theater, projectionists usually show a short clip on refreshments being available, cleaning up your trash, not talking, and turning off your cell phone. I found out today that these clips are called policy trailers. My favorite policy trailer, which I mention almost every time I go to the movies, is the Regal Cinemas roller coaster where the audience rides past the giant boxes of candy and exploding popcorn kernels.
They don’t make them like this anymore… and YouTube is great

That is the best one. It’s funny how we thought in the 90s what trains would look like by 2020.
