 As the director Ferrand (Francois Truffaut) and the Cinematographer  Walter (Walter Bal) are looking over promo stills of Julie Baker  (Jacqueline Bisset), one remarks that he remembers her "from that  movie with the car chase". This is an inside reference to the fact  that five years earlier Bisset played the role of Steve McQueens  girlfriend in Bullitt (1968), a film featuring a groundbreaking car  chase.
