9/10 Despite some chase sequences, the core of the short is a pure situational comedy. Short has some incredible postmodern elements - the dream, body doubles etc. The scene were Buster portray a monkey is one of the greatest physical performances Buster ever gave. A highly influential short (and the MUBI still is quite fantastic!).
The opening dream sequence in which Keaton plays every role - famously including some multiple exposure shots where he played up to nine parts - is a stupendous technical achievement which happens to be very entertaining as well. After the six minute dream sequence, the entertainment is less consistently premium Keaton but there are still plenty of http://letterboxd.com/mharbour/films/diary/
Famous Keaton short in which he plays, in a bravura example of single exposure trickery, every character in the theater, from the orchestra pit and minstrel players, to the stagehand and audience. It's a six minute dream sequence, and the final 15 minutes is pure Vaudeville lunacy (including Buster as a monkey), that defies convention.
One of Buster Keaton's greatest comedies follows the misadventures of a hapless stagehand in an opera house. Exceedingly clever, with some fantastic trick photography that is entirely convincing even today. The highlight is an outstanding dream sequence in which Keaton plays every member of the cast, orchestra, and audience of a minstrel show.
