Gifted sculptor and painter Marcel Duchamp is the subject of this searing documentary that explores one of the most important artists of the 20th century. Dabbling in Dadaism, Surrealism and many other movements, Duchamp allowed his art -- which includes the world-famous "Nude Descending a Staircase No. 2" -- to make provocative and intelligent statements, proving that philosophy rightfully holds a place in high art.
