The Secret Six is a 1931 American pre-Code crime film starring Wallace Beery as "Slaughterhouse Scorpio", a character very loosely based on Al Capone, and featuring Lewis Stone, John Mack Brown, Jean Harlow, Clark Gable, Marjorie Rambeau and Ralph Bellamy.

Bootlegger Johnny Franks recruits a crude working man called Louis "Slaughterhouse" Scorpio as part of the gang of mob boss and lawyer Richard "Newt" Newton.

Then he is prosecuted by a secret group of six masked crime fighters, aided by newspaper reporters Carl Luckner and Hank Rogers.

Harlow and Gable would work together in five other films, Red Dust (1932), Hold Your Man (1933), China Seas (1935), Wife vs. Secretary (1936) and Saratoga (1937).
