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 work is a fascinating journey through all the cinematic cycles that Brazil lived, from the pioneering Belle Époque, through the great studios like Atlântica and Cinédia, Cinema Novo, the urban comedies of the 70's, until the resumption in the late 90's. The documentary is unique, it gives the floor to who really wrote and lived this story intensely.

Seventy critics and filmmakers discuss cinema around the conflict between the artist and the observer, the creator and the critic. Between 1998 and 2007, Kléber Mendonça Filho recorded testimonies about this relationship in Brazil, the United States and Europe, based on his experience as a critic.
