And it was Nikki Reed, this 14-year-old star, who co-wrote the Thirteen screenplay with Hardwicke when she was just 13 herself.
Perhaps this is why this film is so brilliantly well-observed.
It’s actually the Tracy character that’s based on Reed’s own passage into puberty, but Hardwicke didn’t want Reed to play herself so she held auditions for the role. And that’s when she asked Evan Rachel Wood to get into her bed with Reed – the same bed that was used for the Twilight auditions.
I wonder how much she’d get for that bed on e-Bay…
Thirteen is showing tonight – 22nd March – at 10.35pm on ITV1.
