For the uninitiated, Sensurround was invented by Universal Pictures for the aforementioned 1974 disaster film. They wanted audience members to not only watch the earthquake but to experience it as well. If you lived in Peoria instead of L.A., this was probably as close to an earthquake as you were going to get. So somebody got the bright idea to put speakers under the seats. When the earthquake rumbled onscreen, causing destruction to the same scenery its star was chewing, the speakers emitted vibrations in time with the cinematic shaking. No one at Universal realized that this concept, which was used on several of their movies in the 70's, was the equivalent of getting a Dolby-inspired hummer. When I went to see The Exorcist, people passed out in the theater. One woman threw up at my screening. When I saw Earthquake, the audience had a collective tantric orgasm. According to Wikipedia, one person suffered cracked ribs from the arousing effects of Sensurround. That person was probably Sting.

I was too young to appreciate the tactile benefits of Sensurround, so I demand they bring it back. I don't care if they put it on The Sisterhood of the Traveling Pants 2. Just bring it back. It'll make up for the second mortgage I took out to pay for popcorn and soda.
