10. Ganja and Hess (1973)
Director: Bill Gunn
Stars: Duane Jones, Marlene Clark, Bill Gunn
After its release was compromised by a bastardized studio-sanctioned version, most viewers never realized that this was one of the most profound, surreal and horrifying love stories ever made. Breaking barriers of black cinema (and the producers' expectations of just another piece of rehash vampire trash), director Bill Gunn instead delivered a blood-soaked masterpiece that was the only American film screened during Critics' Week at the 1973 Cannes Film Festival...where it won a standing ovation.
