20th Century-Fox "developed" a rival to Universal's gimmicky "Sensurround" sound process (popularized in the theatrical release of Earthquake
(1974)) that was only used for the theatrical release of "Damnation Alley" called "Sound 360." This process was basically a variation of Magnetic-Optical Stereo sound. This technical advancement/gimmick in sound did not last past "Damnation Alley" although it was planned for Walter Hill
's The Driver
(1978) and Damien: Omen II
(1978). If you look at the one sheet of "Damnation Alley" the "Sound 360" declaration and logo are prominent at the bottom. See more
