"Mix together a young, perfectly normal Mid-American couple, a castle full of perfectly looney aliens from the planet Transexual, an assortment of creatures of the night. Then add an audience that talks back and you have the Rocky Horror Picture Show!
What makes this film unique is that you, the audience, can not only participate verbally, but physically as well. Find your favorite character and become that character. Dress up. Get crazy. It's all part of the movie. "
