Mirrors on stage are bad luck.

Is it the fear of the mirror breaking, resulting in seven years of bad luck, or is it the old superstition that mirrors are a gateway for evil spirits to cross over to the world of the living? It is neither. Mirrors are considered bad luck because they reflect light, which is tricky to place on stage without wreaking havoc with the lighting design of a production. Of course, it can be done, but a wrong hit with a spotlight and you could easily have a blinded actor who might just walk off the edge of the stage.
