“ During the early days of Franco's tenure with Harry Alan Towers (1967-1969) there was an occasion, oft remarked upon, when one film (The Girl From Rio) finished shooting a week early, and rather than send the crew home Towers and Franco hastily wrote a new script over the weekend (99 Women), and began shooting it on the Monday. In this case the arrangement was made with the full cooperation of the producer. But did the experience suggest to Franco a possible way of working in the future? After all, 99 Women, conceived in a rush and made without deliberation, went on to become one of Franco's biggest grossing films of all time, spending weeks in the upper reaches of the Variety chart. ”
