 The part had originally been intended for Marilyn Monroe, however problems between Monroe and Fox led to Collins gaining the role.MGM borrowed Collins for "The Opposite Sex" (1956), a musical remake of "The Women" (1939) in which she was cast as the gold digging Crystal, the role played by Joan Crawford in the original.She then starred as a young nun in "Sea Wife" (1956), top-billed over co-star Richard Burton, followed by the all-star "Island in the Sun" (1957), which was a major box-office success.
