Thirteen (2003)

Continuity mistake: When Evie and Tracy go to the park, they walk down a stretch of grass, after Evie makes a drug sale. She stops two guys to make another sale. As she stops them, there is a boy with a helmet and skateboard running behind them. The shot then cuts to a close-up and suddenly the boy is standing next to the two guys. Then the shot cuts again, and the boy is running behind them again. (00:20:35)

Tracy: Mothers, lock up your sons.

Trivia: When Tracy is spinning on the playground equipment in the final scene, she is wearing the clothes that Evie wore when they went to the neighbor lifeguard Luke's house. This may be a call back to her missing Evie after she left or a representation of how Tracy's style changed over time. Also, when Tracy wakes up next to Mel in the end she looks disappointed. And I have come to think that she is upset because she wanted to wake up next to Evie again. (00:49:51 - 01:34:51)

Question: I read that Evan Rachel Wood's character, Tracy, is supposed to be Nikki Reed at the age when she was having the experiences that Tracy went through. Was the character Evie based on a girl that Nikki knew in real life?
