8 x 8: A Chess-Sonata in 8 Movements is an American experimental film directed by Hans Richter, Marcel Duchamp, and Jean Cocteau. Described by Richter as "part Freud, part Lewis Carroll" and filmed partially on the lawn of Duchamp's summer house in Southbury, Connecticut.

Experimental documentary focusing on a day in the life of city workers, featuring montage sequences and repetition to emphasise the monotony of routine office work.
