Underwater!

Johnny (Richard Egan) narrates as he and pal Dom (Gilbert Roland) spring their sunken treasure scheme on Theresa (who turns out to be a Latina Jane Russell), early in producer Howard Hughes' Underwater!, 1955.

In a big payoff scene, Johnny (Richard Egan) dives to the sunken wreck and Theresa (Jane Russell) finally unveils the red suit (featured in the promotional campaign, seen above-decks for the first time) then gets trapped, in Underwater!, 1955, produced by Howard Hughes.

Divers race the clock to find a Caribbean treasure before modern-day pirates can catch up to them in Underwater! (1955).
