One of the more pleasing by-products of the Swinging Sixties, British stage actress Jane Birkin made a huge international impression in 1966 as one of the two nude models (she was the blonde) in Antonioni's existential feature film Blow-Up. Since that time, Birkin has often as not appeared in bisexual or androgynous film roles; in Roger Vadim's Don Juan 73 (1973), she was cast as Brigitte Bardot's lover.
