Two different taglines or slogans were used for the 1979 film, "Caligula". The one used for its original theatrical run was, "What would you have done if you had been given absolute power of life and death over everybody else in the whole world?".
The 1979 film, "Caligula," is a dramatization of the life of the notorious Roman emperor, a man known for his bizarre and perverse excesses, such as appointing his horse as senator and having sex with his sister. The film itself depicts graphic sex and violence. This disgusted some critics, including Roger Ebert. The tagline for the 2002 DVD rerelease makes note of the controversy with the slogan, "The most controversial film of the 20th century is now the most controversial film of the 21st century."
