Movies in the Roaring Twenties: Hollywood became a glittering entertainment industry with star directors like Charlie Chaplin and Buster Keaton. But the gloss and fantasy was challenged by movie makers like Robert Flaherty, Eric Von Stroheim and Carl Theodor Dreyer, who wanted films to be more serious and mature. This was a battle for the soul of cinema. The result: some of the greatest movies ever made.

The explosive story of film in the late fifties and sixties: The great movie star Claudia Cardinale talks exclusively about Federico Fellini; in Denmark, Lars von Trier describes his admiration for Ingmar Bergman; and Bernardo Bertolucci remembers his work with Pier Paolo Pasolini. French filmmakers plant a bomb under the movies, and the new wave it causes sweeps across Europe.

Film in the 1990s enters a surprise golden age. In Iran we meet Abbas Kiarostami, who rethought movie making and made it more real. Then, in Tokyo, we meet Shinji Tsukamoto, who laid the ground for the bold new Japanese horror cinema. In Paris one of the world’s greatest directors, Claire Denis, talks exclusively about her work. The story ends in Mexico.
