Down Periscope is a 1996 American military comedy submarine film directed by David S. Ward, produced by Robert Lawrence, and starring Kelsey Grammer, Lauren Holly, and Rob Schneider along with Bruce Dern, Harry Dean Stanton, William H. Macy, and Rip Torn in supporting roles. Released by 20th Century Fox on March 1, 1996, the film focuses on Lieutenant Commander Thomas Dodge (played by Grammer), a capable, if somewhat unorthodox, U.S. Navy officer who fights to save his career after being saddled with a group of misfit seamen who have been brought together as the crew of his first command, USS Stingray, a rusty, obsolete World War II-era diesel submarine that is the focus of a special naval war game, supervised by a bitter rival (played by Dern) who is fighting to bury Dodge's career by any means necessary.
