Messalina, Messalina
Messalina, Messalina, also known as Caligula II Messalina, Messalina, is a 1977 Italian spoof film.
The film begins with Messalina Anneka Di Lorenzo, the wife of Claudius Vittorio Caprioli, who is now Emperor succeeding Caligula. Most of the film revolves around Messalinas adulterous behavior, while Claudius remains blissfully unaware. Empress Messalina is having sex every man in Rome except her husband Claudius, a traveler who has come to Rome looking for a good time, and a Roman conman. It all ends in a comedic and gory bloodbath when Claudius comes home early and finds an orgy taking place in the palace. Claudius and his soldiers kill Messalina and all of the orgy participants.
