Anderson is a redhead in the film. “The hardest thing I’ve ever done,” she says of her role. “It was three months of real immersion in this person, and it took me a while to shake off.” She wasted no time in going back to her signature blonde. “Until I got rid of the red hair, I was like, ‘She’s got to go. Goodbye, Jean!’ You have to find ways to let go of a character, and hair is a big deal.” A cutaway in the Netflix doc shows a box of Garnier Nutrisse hair colour in a shade called Lightest Platinum. It’s a subtle reminder that Anderson was launched into the showbiz stratosphere as the Playboy Playmate gone ballistic in Baywatch, the latest update of the pneumatic blonde-bombshell archetype whose lineage embraces Jean Harlow, Jayne Mansfield, Lana Turner, Anita Ekberg and Marilyn Monroe, unhappy sex symbols all. A poignant clip from that doc captures Anderson in 1991 as a bright-eyed naif: “This is my time to shine not as a sex symbol, but as an actress. I think I stood back too long.” Faint hope. Years pass and we see her, naive no longer, wearily declaring, “My boobs had a career and I was just tagging along.”
