In the late nineteen-seventies and into the eighties, Brooke Shields was one of the most famous and most controversial people in America. At age eleven, she appeared in the film “Pretty Baby,” playing a child prostitute; by fifteen she was in the heavy-breathing desert-island love story “Blue Lagoon.” She was the face of a series of ads for Calvin Klein jeans featuring notoriously smutty innuendo. Yet Shields herself—rather than the filmmakers and ad men who developed her roles—became the object of fascination and public reproach, as the new documentary “Pretty Baby: Brooke Shields,” premièring on Hulu, demonstrates in detail. Yet, if she was exploited by adults around her when she was young, Shields denies any sense of being a victim. In a conversation with Michael Schulman, she calls hypocrisy on models who criticize their industry. “You’re making money, and you’re selling something, and, in most cases, sex sells,” she says. “ ‘Oh, I’m being objectified.’ You’re a model! That’s the point!”
