Two years of research and visits to collections, cinematheques and museums; almost seventy interviews that generated 30 hours of recorded material; more than two hundred scanned photos and more than one hundred films watched. In total, more than a thousand hours of work were needed to prepare Brazilian Cinema in the 20th Century.

The documentary is unique, it gives the floor to who really wrote and lived this story intensely..
