Cecil B. DeMille: Male and Female (1919)

Male and Female is a 1919 American silent adventure/drama film directed by Cecil B. DeMille and starring Gloria Swanson and Thomas Meighan. Its main themes are gender relations and social class. The film is based on the J. M. Barrie play The Admirable Crichton.
A previous version was filmed the year before in England as The Admirable Crichton.
The film centers on the relationship between Lady Mary Loam (Swanson), a British aristocrat, and her butler, Crichton (Meighan). Crichton fancies a romance with Mary, but she disdains him because of his lower social class. When the two and some others are shipwrecked on a deserted island, they are left to fend for themselves in a state of nature.
The aristocrats’ abilities to survive are far worse than those of Crichton, and a role reversal ensues, with the butler becoming a king among the stranded group. Crichton and Mary are about to wed on the island when the group is rescued. Upon returning to Britain, Crichton chooses not to marry Mary; instead, he asks a maid, Tweeny (who was attracted to Crichton throughout the film), to marry him, and the two move to the United States.
