Let's Live a Little is a 1948 American romantic comedy film directed by Richard Wallace and starring Hedy Lamarr, Robert Cummings and Anna Sten. Written by Howard Irving Young, Edmund L. Hartmann, Albert J. Cohen, and Jack Harvey, the film is about an overworked advertising executive who is being pursued romantically by his former fiancée, a successful perfume magnate, who is also the ad agency's largest client. While visiting a new client—a psychiatrist and author—to discuss a proposed ad campaign, his life becomes further complicated when the new client turns out to be a beautiful woman, who decides to treat his nervous condition.

Hedy Lamarr was an Austro-Hungarian-born American actress and inventor. After a brief early film career in Czechoslovakia, including the controversial erotic romantic drama Ecstasy (1933), she fled from her first husband, Friedrich Mandl, and secretly moved to Paris. Traveling to London, she met Louis B. Mayer, who offered her a film contract in Hollywood. Lamarr became a film star with her performance in the romantic drama Algiers (1938). She achieved further success with the Western Boom Town (1940) and the drama White Cargo (1942). Lamarr's most successful film was the religious epic Samson and Delilah (1949). She also acted on television before the release of her final film in 1958. She was honored with a star on the Hollywood Walk of Fame in 1960.
