Friday the 13th

Hack wrote this spy thriller with high hopes of selling the movie rights, starting a franchise that would spring to the collective mind every time a Friday the 13th appeared on the calendar. When he learned that there was already a series of horror films based on that strategy, he made another of his many failed suicide attempts by jumping out a window but broke his fall by landing on the woman who would become his sixth wife. After they were divorced three months later, Hack said that he wished that he’d stuck with his original title of “Goldfinger.”

Labor Day Seduction

When filmmaker Gary Marshall directed a series of romantic comedies with holiday themes like “Valentine’s Day,” “New Year’s Eve” and “Mother’s Day,” Hack wrote a spec script titled “Labor Day” and sent it to Mr. Marshall’s office. They passed on the project, objecting to the grimmer aspects of the story where a woman invites a man to a holiday barbeque and then locks him in her basement BDSM dungeon, subjecting him to various genital tortures until he admits his love for him. Hack refashioned the story into this novel about young love although he admitted that he didn’t consider it his best work, saying that it was “too sappy.”

Romances of the Macho Men of the Foreign Legion

Hack didn’t mess with success with the third novel in his Foreign Legion trilogy and once again just took the original manuscript and swapped out the many sex scenes with new perversions. As far as his publisher John Kane was concerned, he could have continued with the formula forever but Hack felt that he had said everything he had to say about sexual deviance on the sands of the Sahara Desert and moved on to write about sexual deviance in other locales.
