This is one of the best behind the scenes documentaries a movie history buff is going to see of early motion picture production. It is MGM 1925. It covers every department at MGM at that time. You are not viewing a documentary made today but one made in 1925. Excellent quality. I discovered it was aired on TCM in December 2007. I had "The Smart Set" on my DVR (a silent MGM picture from 1928 with William Haines). I recently watched it and discovered this gem at the end--in between films. It is amazing "living" history from 84 years ago. Every film history class should view this. I liked seeing the people in the film who all seem very much alive, enjoying life and their profession.
