Despite the title, this film has virtually nothing to do with Thomas De Quincey's book. But it happens to be one of the most bizarre, beautiful, and poetic Z-films ever made, and probably the only directorial effort of Albert Zugsmith that is almost good enough to be placed alongside his best films as a producer (e.g., Touch of Evil, The Tarnished Angels, Written on the Wind). Vincent Price stars as the black-clad 19th-century adventurer, involved in a San Francisco tong war and with runaway oriental slave girls; Linda Ho, Richard Loo, and June Kim also figure in the cast, and Robert Hill is responsible for the singularly pulpy script. A claustrophobic fever dream with strange slow-motion interludes and memorable characters, this is the kind of film that you remember afterward like a hallucination; not to be missed. Also known under the titles Souls for Sale and Evils of Chinatown (1962).
