I, Don Giovanni (Italian: Io, Don Giovanni) is a 2009 Spanish-Italian-Austrian drama film directed by Carlos Saura.

The film narrates the life of Lorenzo da Ponte, an Italian Freemason who wouldn't give up his libertinism, despite being ordered to do so as a priest of the Roman Catholic Church. When the Holy Inquisition accused da Ponte of having betrayed the Christian faith through his licentiousness and publication of criticisms against the church (influenced by Casanova), condemning him to the exile, his close friend Giacomo Casanova wrote a presentation letter for Antonio Salieri, before da Ponte had to leave Venice for Vienna. Here, Salieri introduced him to Mozart, and da Ponte wrote le Nozze di Figaro.

At the intervention of Casanova, da Ponte persuaded Mozart to publish a second edition of the Don Giovanni, which was performed in presence of the Emperor Joseph II, to great success.
