'A Busy Day' was the first of the three movies where Charles Chaplin appeared in drag. While in second and third time he played a female impersonator (in 'The Masquerader' he played an actor pretending to be a woman to get work, and in 'A Woman' he pretended to be a woman to get away from his pursuers), then in this one he portrays a real woman - a jealous wife of the husband who starts to flirt with a beautiful girl at the military parade. The film is nothing special (supposedly it was filmed within two hours at the real military parade) - Chaplin is a jealous wife, but she kicks and hits everybody for no obvious reason. Posing in front of the camera and annoying the operator is just the rework of the joke from the 'Kid Auto Races at Venice'. The stunts and gags lack any proper buildup turns 'A Busy Day' just random scenes of people getting hit in the backside by Chaplin and nothing more.
This film can be easily passed on if you're not Charles Chaplin completist or interested to see all his drag performances, from which this is the weakest one. Plus, he looks ugly in this, but that might be done on purpose. Or is it because he plays the character who is ugly on the inside. Of course, the footage of the real parade and warships is interesting to see.
