...The Honeymoon Killers (1969)

The Honeymoon Killers is writer/director Leonard Kastle's one attempt at filmmaking, and it's a doozy. In cinema-verite style, with black and white photography, and emotionless, resonating performances by Shirley Stoler and Tony LoBianco, the film focuses on the sensational 1940s-era murderers referred to as the Lonely Hearts killers. Mistakenly perceived as an exploitation film, there is no blood to speak of and only implied violence but the sum is one movie you won't soon forget.
