1974 American disaster film by Mark Robson
Earthquake is a 1974 American ensemble disaster drama film directed and produced by Mark Robson and starring Charlton Heston and Ava Gardner. The plot concerns the struggle for survival after a catastrophic earthquake destroys most of Los Angeles.
Directed by Robson with a screenplay by George Fox and Mario Puzo, the film starred a large cast of well-known actors, including Heston, Gardner, George Kennedy, Lorne Greene, Geneviève Bujold, Richard Roundtree, Marjoe Gortner, Barry Sullivan, Lloyd Nolan, Victoria Principal, and (under an alias) Walter Matthau. It is notable for the use of an innovative sound effect called Sensurround, which created the sense of actually experiencing an earthquake in theaters.
