Scum of the Earth!

Scum of the Earth also known as Sam Flynn is a 1963 American exploitation film directed by Herschell Gordon Lewis and produced by David F. Friedman. It is credited as being the first film in the roughie genre.

In his autobiography, David F. Friedman wrote that Scum of the Earth was shot in six days. It was filmed in blackandwhite not to save money, but to intentionally give it a dirty look, like an old, scratchedmm stag film. Friedman had the idea of promoting the film a week before its showing by giving theater audiences comic books of the story.Allmovie wrote, Unintentionally funny and poorly photographed, this film certainly has its moments for connoisseurs of bad cinema, but others will find it tawdry and dull. ........
