The Russians Are Coming, The Russians Are Coming is a 1966 American comedy film. Based on the Nathaniel Benchley juvenile novel, The Off-Islanders, it was adapted for the screen by William Rose. The movie tells the Cold War story of the comedic chaos which ensues when the Soviet submarine, Спрут (Sprut, Squid), accidentally runs aground near a small New England town.
Despite being set on the fictional "Gloucester Island" off the coast of New England, the movie was filmed on the California coast, mainly in Mendocino. The harbor scenes were filmed in Noyo Harbor, a small town south of Fort Bragg. Because of the filming location on the West Coast, the dawn scene at the beginning of the movie was actually filmed at dusk.
The submarine used in the movie was a fabrication. The United States Navy refused to loan one for the production and barred the studio from bringing a real Russian submarine, forcing the studio to create their own. It was segmented into four parts, each having its own motor to power it. Upon close inspection while watching the film, the viewer may notice the separate parts as the "sub" floats in the water.
