Very well made documentary about Kubrick's film - includes interviews with Kubrick, McDowell, Burgess, Christiane Kubrick, Jan Harlan, Bernard Williams, Gaspar Noe and others. There are anecdotes as well as thoughtful interpretations here, as we hear the crew recount how the film came to be - and why it was the way it was. How McDowell was cast, where the white outfits with codpieces came from and Gene Kelly's reaction to McDowell are among the nice details to be found.
It's mostly of the talking head variety (no direct BTS footage) but it's still very engaging. Hope your french is up to it!
