The Blue Angel

There's so much in this scene. Where to begin?

There's the clown who always floats around the scene, looking like an angel of death, a depressed prediction of what Prof. Rath will one day become. There is the moment on the floor where we have Dietrich disembodied, becoming just her legs, like meat for the consumption of men. There is the fact that his students are spying on him so though he's falling in love, he's viewed as pathetic and contemptible by the rest of the world (prefiguring when he becomes a literal clown at the end of the film).
