Suzanne was basically at the peak of her fame, such as it was, in the early '70s, pretty much when Patty was at the nadir of her mental health and I'm sure Suzanne, like the rest of Hollywood, tried to stay as far away from Patty as possible.
Early in the film she says to some stud muffin she has just had her way with.
She married her first husband, Troy Donahue, in 1964, and the couple split after eight months of stormy cohabitation.
