Revealing mistake: In the opening scene the Club's dancers are in full-swing, including the tall, lanky gentleman from Lautrec's famous Moulin Rouge poster, the one with the very angular, extended nose and chin. In several closeups it's very plain that the chin is a makeup appliance: the edge of the appliance isn't blended very well with the actor's real skin.

Henri: Well, Jane, what a long road you have traveled. Only a few years ago you were singing for your supper, and here you are a full-fledged star at twenty-nine.
Jane Avril: Twenty-five.
Henri: Of course, I beg your pardon. Twenty-five.
Jane Avril: I have been twenty-five for four years, and I shall stay there for another four. Then I'll be twenty-seven for a while. I intend to grow old gracefully.
