Blackenstein (also known as Black Frankenstein on its theatrical release poster and whose actual on-screen title is Blackenstein the Black Frankenstein) is a 1973 American blaxploitation horror film directed by William A. Levey, and starring John Hart, Ivory Stone, Andrea King, Roosevelt Jackson, Joe De Sue, Nick Bolin and Liz Renay. It is loosely based on Mary Shelley's 1818 novel Frankenstein; or, The Modern Prometheus. Released on August 3, 1973, it was made in an attempt to cash in on the success of Blacula; released the previous year by American International Pictures. However, Blackenstein fared poorly in comparison to its predecessor, with most reviews agreeing that the film was "a totally inept mixture of the worst horror and blaxploitation films".
