La Gueule, the alter ego of Serge Gainsbourg in the 2010 French biographical film Gainsbourg (Vie héroïque). He’s portrayed as a strange, larger-than-life version of Gainsbourg’s darker side.

(La Gueule is not an alter ego, hallucination, or manifestation of another person in this AU. He is an entirely independent human being whose personality and visual identity are inspired by the cinematic character. He has his own life, ambitions, flaws, friendships, history, and future—and doesn't exist merely to orbit another character.)
