On the anniversary of Billy Wilder's birth, take a look at a kite-flying, procrastinating Wilder being interviewed by French film critic Michel Ciment in Annie Tresgot's 1982 documentary. Then settle in this weekend with a stack (or digital cache) of the writer/director's best work. How did he develop his scripts with longtime collaborator I.A.L. "Izzy" Diamond? "To quote Mr. Churchill, it's blood, sweat and tears. It is a drag…. Sometimes we just sit there and wait."
