The Blue Angel

In this scene, the professor comes back to see Lola Lola and I noticed something interesting. The clown that is seen in multiple scenes throughout the film, stares at the professor. Clowns are supposed to be happy and funny but this clown stares at the professor with a solemn look. It's like the clown knows what the professor is getting himself into but he can't warn him about it and that's what makes him sad. It's foreshadowing what the professor becomes by the end of the film. He becomes a sad clown just like the one we saw in the scene.
