There's an unforgettable scene in the Netflix documentary Joan Didion: The Center Will Not Hold. Filmmaker Griffin Dunne asks Didion about the legendary moment when, while reporting a piece on the counter-culture in San Francisco's Haight-Ashbury neighborhood, she came across a 5-year-old girl tripping on LSD.
"What was that like?" Dunne wonders. Didion pauses, and replies, "It was gold." Which is to say that the little girl was great material.
