On April 13, 2011, Les Films 13 production company turned 50. How can one celebrate an anniversary of this sort ? By simply making "another" film that would sum up all the earlier ones. D'un film à l'autre is hence a kind of anthology of the films produced Les Films 13 since the 1960s (short and feature films written and directed for the main part by Claude Lelouch), a best-of of half a century of cinema, going from Le Propre de l'homme to What Love May Bring. A biography in images of a filmmaker as admired as he is criticized. In reality, D'un film à l'autre is more than a series of film excerpts, interviews, and making-of documents (some of which possess an undeniable historical value, like that from A Man and A Woman, or the final performances of Patrick Dewaere).
