Instead it comes when she’s sitting at her dining table and her two daughters, Rowan, 19, and Grier, 17, are explaining why they will never see Malle’s movie. And it’s not when she talks publicly for the first time about being raped in her early 20s by a man she thought wanted to hire her for a film. It doesn’t happen when she’s talking about the time her mother, Teri, agreed for her to pose fully nude at the age of 10 for a Playboy publication nor when recalling her role as a child prostitute a year later in Louis Malle’s 1978 film, also called Pretty Baby. There’s a moment towards the end of Brooke Shields’s new documentary about her extraordinary life, titled Pretty Baby, where you can see her defences come crashing down.
