Visit to Picasso ("Bezoek aan Picasso") is a short Belgian documentary film from 1949 about painter Pablo Picasso, directed by Belgian filmmaker Paul Haesaerts. In an effort to capture the nature of Picasso's creative process, Paul Haesaerts asked the Spanish painter to apply his magical brushstrokes to large glass plates as Haesaerts filmed from the other side. This film actually predated the more famous art film The Mystery of Picasso (1956) by Henri-Georges Clouzot, in which Picasso painted on large transparent canvases as the director filmed from the other side.
