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.
Trivia: When Isabel is setting up chairs at the poetry reading and is confronted by Tellman, you can see copies of "Le Divorce" by Diane Johnson on the bookshelf behind them.
