Warner Brothers replaced the film's planned male leads with their own Warner Brothers Television contract leads who received no extra money to do the film. Warner Brothers felt that casting these performers would attract their fans to the film, while at the same time pleasing the stars who had requested more interesting and different material than they had at Warners. Efrem Zimbalist Jr was given top billing over the four female stars, however in posters produced in some overseas countries his name was shifted down in favour of the better known Shelley Winters and Jane Fonda.
