I have all his Vitaphone talkies archived ready to watch. I've only seen 2 of them in the past. I enjoy spotting landmarks from my old Brooklyn neighborhood. The studios were in a different area than where I lived, but they did travel to different locations where I've spotted buildings from my neighborhood. I have a silent digest (about 8 minutes) of BUZZIN' AROUND in Super 8.
Most of what I've seen of his films were the ones with Buster Keaton. I recently acquired 3 other shorts of his on film from Blackhawk -- I think all with Mabel Normand -- I wasn't that impressed. I do love THE ROUNDERS short he did with Chaplin, though.
