Henri-Georges Clouzot, the French director of the masterpieces "Les Diaboliques" and "Le Salaire de la Peur" convinced his friend Pablo Picasso to make this documentary, painting twenty paints in front of the cameras. Using some special technique, Clouzot filmed from the other side of the canvas or stop-motion, and the result is this movie, where two geniuses are gathered: one behind and the other in front of the camera. In accordance with the information on the DVD, the canvases have been destroyed in the end of the shootings. Further, in 1984, the French government declared this documentary a national treasure. Clouzot and Picasso deserved this beautiful homage. My vote is eight.
Title (Brazil): "O Mistério de Picasso" ("The Mystery of Picasso")
