A transcript of movie icon Rock Hudson's gay confession to his wife Phyllis has been obtained by The Hollywood Reporter journalists.

Late private detective Fred Otash's daughter, Colleen, has offered the publication's editors access to her father's secret files, which feature a word-for-word transcript of the awkward January, 1958 conversation screen idol Hudson had with his wife, who demanded to know if he was gay.

According to Otash's journal, she said, "I'm not condemning you, but it seems that as long as you recognise your problem, you would want to do something about it."

Phyllis also quizzed her husband about his performance in bed, asking him if he lasted longer with boys, to which Hudson responded, "Well, it's a physical conjunction (sic). Boys don't fit. So, this is why it lasts longer."

She adds, "Everyone knows that you were picking up boys off the street shortly after we were married and have continued to do so, thinking that being married would cover up for you."

But the then-32-year-old actor said, "I have never picked up any boys on the street. I have never picked up any boys in a bar, never. I have never picked up any boys, other than to give them a ride."

According to Otash's daughter, Hudson's wife hired the detective to check on her husband after first suspecting he was gay following a chat with the actor's therapist, and asked him to secretly record his confession.

The transcript is one item in a collection of fascinating tapes, journals and paperwork that have been locked away inside a storage unit in California's San Fernando Valley - until now.

Otash was reportedly the inspiration for Robert Towne's private eye when he wrote the Oscar-winning screenplay for 1974 film Chinatown, starring Jack Nicholson.
