Considered by many to be one of the greatest films ever made, Alfred Hitchcock’s late-50s masterpiece Vertigo has one of the most iconic uses of the double in all of cinema history. The film is an unpredictable and chilling thriller that doubles as a mournful meditation on love, loss, and human comfort. The film stars James Stewart as former police detective John "Scottie" Ferguson. Scottie is forced into early retirement because an incident in the line of duty has caused him to develop acrophobia (an extreme fear of heights) and vertigo (a false sense of rotational movement). Scottie is hired by an acquaintance, Gavin Elster, as a private investigator to follow Gavin's wife Madeleine (Kim Novak), who is behaving strangely. After saving her from suicide, Scottie begins to fall in love with her, and she appears to feel the same way. However, tragedy strikes, and with each twist in the film’s second half our preconceptions about the characters and events begin to alter. Accompanied by Bernard Herrmann’s hypnotic score, vibrant cinematography from Robert Burks, and masterful direction from Hitchcock, Vertigo is our pick for the greatest film involving doubles.
