Casanova is a 2005 American romantic film directed by Lasse Hallström starring Heath Ledger and loosely based on the life of Giacomo Casanova.
A young woman tearfully leaves her son (Eugene Simon) to live with his grandmother and promises to return for him someday. Several years later, in 1753, in Venice, Casanova (Heath Ledger), is notorious for his promiscuity with women, his adventures being represented in puppet theatres around the city. The Doge, the ruler of the city, is sympathetic to Casanova, but cannot be too lenient on him as to avoid trouble with the church. He warns Casanova that he must soon marry or he will be exiled from the city.
