In 1958, MGM released this film on a double bill with The Safecracker (1958) and the tag line "UNDERSEA PERILS and UNDERCOVER THRILLS!"
The USS Grasp was used in the filming of this movie. During filming, Dan Dailey insisted on bringing a sizable amount of beer. However, it was against naval policy to drink on a navy vessel, so he arranged for a "camel" (a platform tied to the side of the ship to allow the ship to be painted, etc.) so that the crewmembers could drink the beer. They would go down on the camel, drink their fill and then climb back onto the ship.
