Roman Polanski's "Amsterdam" segment was removed, according to a title card in the film between the first and second segments, at the request of the director. It has not been restored, although clips appear in the trailer.
At the beginning of the Marrakech episode, Jean Seberg is on the phone and says that Romain has gone to Casablanca. That same year (1963), the American actress had married the French novelist Romain Gary.
