Diamond Head, also known as Honolulu Hustle, is a horrific adult feature film that insults the intelligence and challenges the libido of anyone who watches the film. Many of the cast members look like they were cast at the local soup kitchen and the attempts at jokes will only appeal to the most vacuous of viewers. Diamond Head isn't recommended under any circumstances. Vinegar Syndrome has done a decent job with their streaming-only edition of Diamond Head on Exploitation.TV with decent audio and video quality.
