I just saw on a Spanish newspaper website that a movie about Jane Birkin's life is being made. In case you don't know, she was married with John Barry. And Barry is gonna be a role in the motion picture performed by Ian Hurt.
Jane was married with John Barry (I think they met while filming "The Knack"), but she left him when she met Serge while filming the film "Slogan" in France in 1968. She later divorced Serge (with whom she has a daughter Charlotte) and then married the French director Jacques Doillon.
