Erotikon (1920 film)
Erotikon is a 1920 Swedish romantic comedy film directed by Mauritz Stiller, starring Tora Teje, Karin Molander, Anders de Wahl and Lars Hanson. It is based on the 1917 play A kék róka by Ferenc Herczeg. The story revolves around an entomology professor obsessed with the sexual life of bugs, and his easygoing wife who is courted by two suitors. Plot
Leo Charpentier, entomology professor, is interested in polygamy among beetles but hasn't noticed that his wife Irene is having an affair with his best friend, sculptor Preben Wells, and flirting with an aviator, Baron Felix. They go to a ballet – Schaname, about the shah's wife who tries to seduce his best friend: he demurs but the shah kills him anyway. Leo says he'd have preferred a happy ending. In a shop, Irene hears a woman charging a fur to Preben and walks out, jealous. Preben sees Felix taking a woman home, and thinks it's Irene, and is also jealous. He goes to Irene's home and accuses her; she tells Leo she's deceived him, and walks out. Preben finds Felix's friend wasn't Irene at all. To atone for his mistake, he tries to return Irene to Leo – but when he finds her, and explains that the woman buying the fur was his model, it's they who make up. Irene phones Leo to point out that his niece Marte loves him and will cook the meals for him she never did herself. Cast
