Italian cult favorite Dario Argento (The Bird With the Crystal Plumage) directed this violent and offbeat horror feature (1987) set in the celebrated La Scala opera house, where an unorthodox production of Macbeth is being presented. After the diva is injured, her understudy suffers a string of brutal attacks and tortures, among them being forced to watch the murder of her lover. Also known as Terror at the Opera; different versions run 88 and 107 minutes.
