Susan Lenox (Her Fall and Rise) is a 1931 American pre-Code Metro-Goldwyn-Mayer film directed and produced by Robert Z. Leonard and starring Greta Garbo and Clark Gable. The film is based on a novel by David Graham. It is the only screen pairing of Garbo and Gable, who did not like each other. The notoriety of the novel alone caused British censors to ban the film's release. Following several edits, it was finally approved in the UK with a new title, The Rise of Helga.

Robert Zigler Leonard was an American film director, actor, producer, and screenwriter.
