Blue Angel is a pre-World War 1 German film directed by Joseph Von Strindberg about an eccentric professor who marries a destitute cabaret singer named Lola Lola. This changes his life as he leaves his academic career behind and transforms into a clown-like figure subjugated to Lola's libido. The film explores the professor's psychological transformation and subjugation to Lola, representing the subjugation of his masculine psyche to the anima. It is seen as emblematic of Weimar Germany and uses settings of stairs, streets, and indoor locations to tell a story of humor, tragedy, and transient states of mind.
