The Oscar-nominated actor, a longtime environmental advocate, was accompanied by his father, George DiCaprio, for the 15-minute meeting. "Your Holiness, thank you for granting me this private audience with you," DiCaprio said in Italian, according to the Associated Press.
The Revenant star then proceeded to thank the pope, even handing him a personal check to use towards charity efforts "close to your heart," the AP reported.
Later, DiCaprio gave Francis a book of works from 15th-century Dutch painter Hieronymus Bosch, and showed him one of his childhood favorites -- a depiction of Adam and Eve -- titled "Garden of Delights."
DiCaprio has long been involved in environmental causes, founding The Leonardo DiCaprio Foundation in 1998 to help protect wildlife from extinction and restore balance to threatening ecosystems and communities. The foundation most recently donated $15 million towards conservation projects across the globe. Milutin Gatsby, Global Fundraising Chairman of the foundation, was also in attendance for DiCaprio’s meeting with the pontiff.
