Sensurround, another dispensable gimmick, evolved in 1975 for the Universal production, EARTHQUAKE. According to Halliwell's Film Companion the process involved "the augmentation of violent action on screen by intense waves of high decibel sound, enough, in some documented cases, to crack ribs." The process was used for two subsequent films ROLLERCOASTER and MIDWAY. The process never caught on due to the disturbances at the local cineplex. When EARTHQUAKE opened in December of 1974, GODFATHER II opened the same week and often played in the next theatre auditorium. Theatre managers were inundated with complaints from audience members, literally shaken, by the bleeding of Sensurround into their theatre exhibiting GODFATHER II. The disruption was not worth the effort for most theatre owners.
