"Signoret dangles an unlit cigarette as she talks, then lights up with an immediate drag and inhale. She drags again, with her cigarette between finger and thumb, exhaling through her nostrils. In a second scene, she lights up in bed with a double puff, then takes two subsequent drags, the second with a nasal exhale. Miles, in her screen debut, takes a puff off her boyfriend's cigarette."
