The producers had a very difficult time persuading Victoria Principal to agree to an interview. She and Andy Gibb were romantically involved off and on for eight years. But since his death she had never agreed to an interview about their relationship. The first time the producers contacted her, she flatly refused. A week later, her agent called to say she would talk very briefly about Andy but nothing about his drug abuse. The following week, the agent called saying that she would not do the interview after all. The producers were devastated because they knew episode would not be good without Principal's involvement. As a last resort, they sent a two-page letter explaining why she was essential to the proper telling of Gibb's story. A week later, she finally agreed to do an in-depth interview.
