Myra Manibog was only 13 years old when her mother took her to see Rey Dela Cruz, who promptly hired her to replace Myrna Castillo, who had walked off the set of this movie. Told that she was 17, both dela Cruz and Celso Ad. Castillo agreed to use Manibog as a stand-in for Myrna Castillo in her remaining scenes, which included one in which she was required to simulate masturbation. Years later, Manibog would reveal that she had been raped by a member of the production crew while filming this movie.
