Law of the Tropics is a 1941 American drama film directed by Ray Enright and starring Constance Bennett, Jeffrey Lynn and Regis Toomey. By the time Bennett made the film, her career was in steep decline.The film is loosely based on the 1935 movie Oil for the Lamps of China, but the setting is changed from China to the Amazon jungle, and the tone is somewhat lighter. The conflict between a man's conscience and his corporate loyalty, which is a principal theme of the original, is less important in this film.
