The Bride Wore Black

Truffaut has stated that this elegant detective thriller, based (like his Mississippi Mermaid) on a novel by Cornell Woolrich, was an attempt to reconcile his two cinematic idols, Alfred Hitchcock and Jean Renoir. It's about Julie Kohler (Moreau), whose husband is inexplicably shot dead on the church steps after their wedding. Truffaut follows Julie's systematic and deadly revenge with a light, idyllic style as she ruthlessly hunts and kills her victims (by methods which include pushing the first over a balcony, poisoning the next, and suffocating the third). Perhaps the mixture of crime fiction and Renoir never quite jells, but it's all highly entertaining, and Hitchcock buffs will enjoy picking out the many echoes (of Marnie especially).
