Cheap(2005)

Driven mad by his failure to sell a profitable film to the porn industry, a director decides to create authentic snuff films with the assistance of two teenage runaways and a perverted cameraman. When the films bring in a profit through an amateur internet production company, they begin to see the film industry for what it is: a world of backstabbing and double-crosses. The twisted filmmakers then extract their own form of graphic revenge on the people who made them successful.
