An excellent overview of Buster Keaton's life and work. The man was such a genius and seeing this touching documentary made me smile. I liked seeing all the miscellany and smaller things he did in his later life, even the commercials, because I had never seen them before. I also liked getting a little excerpt out of so many of the early two-reelers, and of course those extraordinary moments from his major works. I'm not sure about all the choices Bogdanovich made in terms of the celebrity interviews and would have preferred a little more depth in places that didn't get it, but it does show the scope of the influence Keaton had. In the end I appreciated the balance in the documentary, between all of the little clips and rare bits (running the risk of turning attention away from the major films) and the truly amazing physical comedy in those epic moments (running the risk of just becoming just a montage of film clips). It's not perfect, but I saw and learned new things, and was touched and inspired afterwards.
