Ossi, the teenage daughter of a wealthy Berliner, likes playing poker, smoking and drinking. Her guardian is not amused; he swears he will teach her mores. Ossi gets the chance to buy a dress coat and formal mens' clothing for herself, cross dresses and goes off on a spree: it has to be the Mäusepalast, a pleasure hall where the champaign flows. Here she meets her guardian, and things get interesting. This outing by Lubitsch and Ossi Oswalda is considerably better than 'The Oyster Princess', which I watched a while ago. It was clearly intended to help the audiences forget the war that was still raging in the summer of 1918. The film depicts a peaceful, wealthy world, with food plentiful and young men in abundance (and without war injuries), a world where pre-war life has returned, including well dressed people on the underground and motorcars and hackneys on the streets. The acting is actually good. Ossi Oswalda fits the role to perfection, and her guardian (Curt Goetz) does likewise very well. The picture has wit and tempo and is surprisingly open about homosexuality - surprisingly because I did not expect this of a film made in imperial Germany (the censors banned it for underage audiences, though). Contemporay critics were rapturous, and newspapers reported gales of laughter. I managed to stay calm while watching it, but still, it is a good film.
