Based on a shocking true story and shot in frills free documentary-style black and white by the confident and inspired Leonard Kastle – in his sole foray into filmmaking – The Honeymoon Killers is a stark portrayal of the desperate lengths to which a lonely heart will go to find true love. A film about subterfuge and our addiction to affection, the film was brilliantly remade by Mexican auteur Arturo Ripstein as Deep Crimson.
