A 1956 film by French filmmaker Henri-Georges Clouzot about the art of Spanish painter Pablo Picasso (the original French title is Le mystère Picasso). The film shows Picasso in the act of creating some drawings and paintings for the camera on glass plates, beginning with simple marker drawings before progressing to to full scale oil paintings. The documentary won the Special Jury Prize at the 1956 Cannes Film Festival.
Notably most of the art produced for the film was subsequently destroyed, meaning that it now only exists on film, only a few pieces survived and now exist in collections. The French government has taken over the responsibility of preserving the original negative and has declared the film an official French national treasure.
