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)
Trivia: "Selby Wall", played by Christina Ricci, is a totally fictional character. She does not exist. Wuornos' lover was Tyria Moore, who is tall and stocky and looks nothing like Ricci. There is evidence that Wuornos told Moore about at least one of the murders she committed (Richard Mallory in November 1989) and she didn't report it. She agreed to make the phone call to Wuornos, taped by the police, in exchange for immunity from prosecution. This is correctly depicted in the film.
