Seasoned serial director Spencer Gordon Bennett helmed this story of a one-eyed, octopoidal space alien, wreaking havoc upon atomic subs at the North Pole. The monster is determined to take over the world, though it seems ill equipped for that purpose. Heroes Arthur Franz, Dick Foran, and Brett Halsey head underwater to neutralize the aliens submerged flying saucer. The cast is peopled with such veterans as Tom Conway, Bob Steele, Victor Varconi, Selmer Jackson, and Jack Mulhall. Movie buffs may wish to take note of the exterior scenes in Atomic Submarine; several of them are played out in front of the easily recognizable studios of Allied Artists, formerly Monogram and later the home of LAs PBS channel 28. ~ Hal Erickson, All Movie Guide
