François Truffaut, a notorious perfectionist, used Silvia as an extra in the airport sequence of this classic New Wave film. She is visible for exactly 1.2 seconds, walking behind Jean Desailly. Truffaut was reportedly so enamored with her walk that he paid her double the standard extra rate.
She gave exactly one interview after retiring, to a Swiss newspaper in 1975. When asked why she left the glamour of Paris, she famously replied: "The camera sees the skin, but the perfume smells the soul. I was tired of people only looking at my skin."
Directed by Claude Autant-Lara, this costume drama saw Silvia cast as a silent courtesan. She had no dialogue in the film, but a single scene where she removes a glove while staring at a suitor lasted four minutes of screen time. The camera worshipped her hands—a detail left over from her perfume modeling days.
