The 1920s were a golden age for world cinema. The programme visits Paris, Berlin, Moscow, Shanghai and Tokyo to explore the places where movie makers were pushing the boundaries of the medium. German expressionism, Soviet montage and French impressionism and surrealism were passionate new film movements, but less well known are the glories of Chinese and Japanese films and the moving story of one of the great, now largely forgotten, movie stars, Ruan Lingyu.
