Final Flesh

Final Flesh is a 2009 American independent post-apocalyptic surreal comedy horror film directed by Ike Sanders, written by Vernon Chatman, and produced by PFFR. The film was made by sending the most deliberately absurd and ridiculous scripts to four different companies that specialize in making custom fetish pornography and having the porn actors act out the scripts, which include plenty of nudity, with short scenes of masturbation being the closest they ever get to pornography. Final Flesh tells a very loose story involving a family who live near ground zero, where a nuclear bomb is scheduled to hit. The film is composed almost entirely of non sequiturs, intentionally designed to be as random and nonsensical as possible.
