The legendary filmmaker had wrapped a six-city U.S. tour in support of 'Megalopolis' in partnership with Live Nation at San Francisco's Palace of Fine Arts on Friday night.

Francis Ford Coppola, the acclaimed American director of "The Godfather" movies and "Apocalypse Now," underwent a non-emergency cardiac procedure in a Rome hospital and is doing fine, he and a U.S.-based representative said on Tuesday.
