Caligula is a steamy, sexual, historical epic about corruption, greed, and murder in ancient Rome. The story is about the villainous Emperor Caligula (Malcolm McDowell) and his cruel and bizarre reign over one of the greatest cities to have ever existed. The film dares to touch upon, and show in great detail, his incestuous passion for his sister, his unsanctioned marriage to one of Rome's most prominent prostitutes, and his gruesome imagination when it came to dealing with those who opposed him. Proposed as possibly one of the most controversial films of all time and being marked by critics as "overacted' and "pornography" the epic does a startling good job of depicting the gritty time period and boasts and all-star, top-notch cast. Some of the notables include actors Teresa Ann Savoy, Guidi Mannari, John Gielgud, Peter O'Toole, Helen Mirren, and John Steiner. The film was 160 minutes in length and includes sex scenes that leave nothing to the imagination.
