Jean-Luc Godard, then a film critic for Cahiers du cinéma, first saw Karina in a series of Palmolive ads in a bathtub covered in soapsuds. He was casting his debut feature film, Breathless. He offered her a small part in the film, but she refused when he mentioned that there would be a nude scene. When Godard queried her refusal, referring to the supposed nudity in the Palmolive ads, she is said to have replied "Are you mad? I was wearing a bathing suit in those ads — the soapsuds went up to my neck. It was in your mind that I was undressed."
I really hope that quote is true, because it may be one of the coolest things I've read.
