As stated in a 5 May 1978 HR brief, Jacqueline Bisset was displeased by Lone Star's exploitation of her nude love scene. HR noted that Secrets was initially purchased by Lone Star to be converted into a pornographic short film, and Penthouse, Playboy and Hustler were reportedly bidding up to $60,000 to acquire still photographs from the picture. A 13 Mar 1978 Box advertisement for the R-rated film offered distributors a $10,000 challenge to disprove Bisset's contention that she did not appear in the disputed nude love scenes, using the controversy to sell the picture to exhibitors.
