mission is a success, and soon Lawrence is recuperating beside Creighton. Finally won over by Lawrence's bravery, the men show their acceptance of him by asking him to sign the portrait they have drawn of Cassidy to present to his widow. Cast Richard Widmark as Lt. Cmdr. John Lawrence Dana Andrews as Chief Jake Flannigan Gary Merrill as Lt. Cmdr. Pete Vincent Jeffrey Hunter as "Pappy" Creighton Warren Stevens as Ralph Hodges Robert Wagner as Lt.

Bill Doyle Henry Slate as "Sleepy" Production Producer Paul Short of Allied Artists protested the use of the title The Frogmen by Twentieth Century-Fox, asserting that he had established prior claim to it. Eventually, Short dropped his claim and Twentieth Century-Fox was allowed to use the title. Short's production was never made. Several major studios were interested in producing films about the Underwater Demolition Teams, but only Twentieth Century-Fox obtained an exclusive guarantee of cooperation from the U.S. Navy. Henry Hathaway, one of the studio's most well received directors, was originally set to direct the film, which was to feature Millard Mitchell in a starring role. Richard Conte was also originally set to play "Pete Vincent", while Jack Elam was first cast as "Sleepy", and Craig Hill was set to play "Lt. J. G. Franklin". Assistant director Dick Mayberry briefly filled in for director Lloyd Bacon when Bacon fell ill with influenza. Producer Sam Engel wrote an original story, titled "Frogmen in Korea", as an intended follow-up to The Frogmen, but the project soon dissolved. A one-hour television remake of The Frogmen, titled Deep Water, was broadcast in May 1957 on the 20th Century-Fox Hour. The program was directed by Roy Del Ruth and starred Ralph Meeker (Lawrence), James Whitmore (Flannigan), and Richard Arlen (Vincent). Because working conditions for The Frogmen were deemed too "riotous" for women, all female roles were written out of the screenplay and none appeared in the completed film. Jack Warden makes an uncredited appearance in the beginning of the film as a crew member of the transport ship. Co-star Gary Merrill, in the role of the captain of UDT-4's transport ship, delivers the line of dialog, "Looks like you've got what amounts to a legal mutiny on your hands", that is virtually identical to a line that he spoke two years earlier in the World War
