this is a "National Film Board of Canada" documentary.it chronicles some of the the making of "The Railrodder",a short film that Keaton did late in his career .it also gives some insight into Keaton and his early life.i thought this was a very good documentary.it was well written,humorous and entertaining.it's just under 1 hour,but there is a lot of info in that time.it is a bit sad to watch,as Keaton is clearly in the end stages of his life.in fact,he died the next year(1966).nevertheless, i think the filmmakers did a good job with the film.some of Keaton's Genius is still evident in the film,at least to me.unlike many documentaries,which tend to be drawn out and boring,this 1 is not,at least in my view.if you are a Keaton fan,you might like this documentary.i am,and i give this film 9/10.
