Trivia: An American Crime
- Adaptational Attractiveness: In real life, Gertrude looked like this◊.
- Adapted Out : Gertrude had seven children, while she has six in the film.
- All-Star Cast: In addition to Page and Keener, James Franco stars in the film.
- Destroy the Abusive Home: The ultimate fate of the Baniszewski home. While plans were made to restore the house as a shelter for abused girls, funding fell through, with many in the community blaming lack of donations on the location being too heavily overshadowed by the murder. Two years after the film's release and almost forty-five years after Sylvia's murder, the house was demolished.
- Dueling Movies: The Girl Next Door, a more extreme adaptation of the Likens case, based on the novel by Jack Ketchum, was also released in 2007.
- Dyeing for Your Art: Ellen Page effectively starved herself for the role of Sylvia.
- Retroactive Recognition : Carole from Glee (Romy Rosemont) as Sylvia's mother, Evan Peters as Ricky.
- Social Services Does Not Exist: Very nearly literally. Many laws regarding mandatory reporting of suspected abuse came into being directly because of this case.
