Given my handle and one major hobby of mine, I suggest folks watch "The Railrodder". It was one of Keaton's final film roles. If you have Netflix, they do have it from time to time and I suggest renting it as the quality of video is much better.

The short has slapstick and I am sure some don't like it much, but watch it for the filming locations and trackwork.
The making-of video is a bit long and can tire some, but again, watch for the production scenes. There is just no way in todays world this type of film could be made. Keep this in mind while enjoying.
