 Because Elizabeth Taylor (I) (qv) wanted to be near husband  Richard Burton (I) (qv), who was at the time filming  _Staircase (1969)_ (qv) in Europe, she demanded this film, with its  Las Vegas setting, be filmed in Paris, France. The studio agreed,  thereby increasing the budget considerably as detailed American  streetscapes, casinos, apartments and supermarkets had to be  recreated in Paris. In the end (after 86 days shooting in Paris) the  company had to move to the real Las Vegas anyway for ten additional  days of intensive shooting.
