One of cinema’s living legends, at 85 years old, filmmaker Francis Ford Coppola (“The Godfather,” “Apocalypse Now”) has finally made “Megalopolis,” an ambitious sci-fi epic he’s been dreaming of making since the 1980s. With the film set to premiere at the Cannes Film Festival later this month, in a matter of days, French distributor Le Pacte has released the first look teaser of the movie.
