Film scholars Jean-Paul Berthomé and François Thomas have called '' Don Quixote '' " the archetype of an unfinished Welles film , unfinished because it was unfinishable . … Welles is almost certainly alone among major filmmakers in having invented the means to allow himself to assert his full right not to show his work to the public until he judged the moment had come , even if that meant he never showed it at all . " In May 1986 , the first public exhibition of the '' Don Quixote '' footage was shown at the Cannes Film Festival . The footage consisted of 45 minutes of scenes and outtakes from the film , assembled by the archivists from the Cinémathèque Française and supervised by the director Costa-Gavras
