Tehran, Iran (CNN) -- The son of Oscar-winning director Oliver Stone converted to Islam in a ceremony in central Iran, a national news agency reported.
Sean Stone became a Shiite Muslim in the city of Esfahan Tuesday and chose Ali as his new Islamic name, the semi-official Fars News Agency reported.
"The conversion to Islam is not abandoning Christianity or Judaism, which I was born with," Stone told Fars News Agency. "It means I have accepted Mohammad and other prophets."
He did not say why he converted.
Stone, 27, is also a filmmaker and has collaborated on his father's projects. His father is Jewish and his mother, Christian.
Oliver Stone directed "Platoon," "Born on the Fourth of July" and "JFK."
