I just watched The Play House which was the first film that was presented in the "Industrial Strength Keaton" DVD collection of various Buster Keaton films from the silents to the end of his life. The first half where he appears in various incarnations of himself was quite impressive especially when 9 of him appear together in the same frame. Some amusing, if not hilarious, gags occur there. The rest of the short has Buster being an actual stagehand/performer who goes through more hilarious mishaps that has to be seen to be believed. I especially loved the way he put out a man's fiery beard or got a woman out of a water tank. Not to mention how he impersonates a monkey. Or how he tells one twin sister from another. So on that note, I highly recommend The Play House.
