César Troncoso began studying acting in the late 80s at the age of 25. During his time at theater school he formed a comedic duet with Roberto Suárez. Together they worked the local night clubs, parties, and rock concerts.
Upon graduation he began an uninterrupted theater career, having to this day approximately 30 plays under his belt. The majority of these plays took place in non-conventional locales (train stations, stables, family homes, parks...) He travelled with many of these plays to numerous international theater festivals (Caracas, Bogotá, Buenos Aires, Santo Domingo, Porto Alegre). In 2004 César won the Florencio prize for Actor of the Year, awarded by the Uruguayan Association of Theater Critics. After working in many shorts, he made his feature-film debut in 2003 with a lead role in Guillermo Casanova's The Trip Towards the Sea (El Viaje Hacia el Mar). For this role he received the Revelation prize and Best Actor of the Year Award presented by the Association of Uruguayan Critics. In addition to his starring role in THE POPE'S TOILET, César also appears in Lucía Puenzo's Cannes-winner XXY (Year 6, Film 5).
