The Motorcycle Diaries star Rodrigo de la Serna is set to portray Pope Francis on the big screen in a new biopic.

The Argentine actor has been cast in the lead role in The Lake House director Alejandro Agresti's forthcoming project, Historia de un cura (A Priest's Tale).

The film will document Pope Francis' upbringing as Jorge Mario Bergoglio in Buenos Aires, Argentina and his election as the new leader of the Catholic Church in March (13), following Pope Benedict Xvi's resignation due to failing health.

A release date for the movie has yet to be announced.
