This documentary brings a lighting on the originality and the specificity of the actor-author Pierre Richard, improbable synthesis of the talking ant silent films, heir to Buster Keaton for the gestural one and the expression of the body, and to Groucho Marx for the puns and the burlesque verbal one. Conceived like a voyage inside the universe of Pierre Richard, "the Art of unsteadiness" makes it possible to better understand its step, its method of actor, director and gag man. With through many testimonies, extracts of films and archives documents, drawn up here the portrait of one of the large last burlesques.
