Tonight is Part 6, which, like the others, has an absurdly long title: 1953-1957 – The Swollen Story: World Cinema Bursting at the Seams. And it has a swollen focus to boot, trying to cover, and explain, a global explosion of innovative cinema, including several from France and Japan. In the latter country, the films of director Akira Kurosawa, including his landmark 1954 movie Seven Samurai (pictured here), proved massively influential on a world scale.
