"Three or four scenes, as I recall, smoking Marlboro reds. First is in a bedroom after a sex scene, she asks her lover to light her a cigarette. He does so, places it between her lips, and she exhales through her nostrils in profile. Another in a nightclub, okay but not great. The last scene is the best, she takes several drags with visible exhales, including thick secondary nostril exhales, as she photographs (and tries to seduce) the stripper from the aforementioned nightclub. Great 60s-style Eurotrash erotic fun."
