Based on a short story by Daphne du Maurier, this film is one of the greatest English horror movies of all time. It is particularly notable for its setting - Venice. John Baxter (Donald Sutherland) and his wife Laura (Julie Christie) are in mourning for their young daughter, who drowned tragically near their home. John takes a job in Venice so that the couple can leave the past behind, but, unfortunately, the past is not easily forgotten. While John begins to see unsettling visions of a young girl in a red coat running through the Venice streets, Laura learns from an elderly psychic that her husband is in grave danger. What follows is an eerie, erotic mystery that builds to a shockingly horrific climax.

It is considered by many to be one of the most daring and influential motion pictures of the 1970s. The cinematography was groundbreaking, and many of the most beautiful scenes were taken in one shot. The use of colour in the film is also notable, with all but red being muted, and icy blues and greys becoming prominent as John's search becomes more frustrating.

In the film Venice is a character in its own right - caught in faded off-season grandeur and turned into a labyrinth of dead-ends and winding back alleys. There is also great irony in the idea of the couple trying to come to terms with their daughter's death in a city which is slowly sinking beneath the waves. Anyone who has been to Venice off-season will know what a haunting place it can be.
