Devil and the Deep is a 1932 American pre-Code drama film directed by Marion Gering, based on Maurice Larrouy's novel (Sirenes et Tritons), and starring Tallulah Bankhead, Gary Cooper, Charles Laughton and Cary Grant.

[1] Charles Sturm (Laughton) is a naval commander whose jealousy and abuse makes life miserable for his wife Diana (Bankhead).

After Charles falls into another fit of paranoid rage and strikes Diana, she wanders off into the streets during a festival and soon encounters another officer, who turns out to be Jaeckel's replacement, Lieutenant Sempter (Cooper).

In a detailed and substantially accurate technical sequence, Diana and the crew exit through the sub's escape trunk using Momsen lungs, and are rescued at the surface.

Refusing to leave the ship, Sturm stays behind and lapses into raving insanity; he opens a watertight door to let in the sea, laughing maniacally as the water rises.
