The Frogmen (1951) 蛙人海底战

The Frogmen is a 1951 black-and-white film made by Twentieth Century Fox. It is based on operations by United States Navy Underwater Demolition Teams, popularly known as "frogmen", against the Japanese Army and naval forces in World War II. It was the first such movie about scuba diving and became a popular cultural hit.

The film opens with this written statement: "This is a true story based on incidents which occurred in the latter part of World War II. It deals with one of the most hazardous and unique branches of the Armed Forces...the Underwater Demolition Teams. This film could not have been produced without the active cooperation of the Department of Defenseand the United States Navy."

The new commander of a Navy Underwater Demolition Team--nicknamed "Frogmen"--must earn the respect of the men in his unit, who are still grieving over the death of their former commander and resentful of the new one.
