Arthur Marks was the director behind one of my favourite blaxploitation movies, "Bucktown" with Fred Williamson and Pam Grier. He also helmed the late entry Grier vehicle and relatively tame "Friday Foster" but was also responsible for the oddity called "J.D.'s Revenge" which combined horror elements with blaxploitation, making it one of the few films to do so outside of "Abby" and "Sugar Hill".
This is great stuff. Filmed on location in Motown.
