Confessions of an Opium Eater (also known as Souls for Sale, Secrets of a Soul and Evils of Chinatown) is a 1962 American crime film directed and produced by Albert Zugsmith and starring Vincent Price as Gilbert de Quincey, a nineteenth-century adventurer who becomes involved in a tong war in San Francisco. It was written by Seton I. Miller and Robert Hill, loosely based on the 1821 autobiographical novel Confessions of an English Opium-Eater by Thomas De Quincey. Price also narrated the film, whose evocative cinematography resembles a nightmare. The film was something of a departure for Price; the prolific actor never performed another role that involved so much physical action.
