The photos in Pauline's bedroom in the film are real photos of Juliet Hummer herself.
The director Peter Jackson himself showed up in the film: he played the homeless man who was kissed by Juliet outside the movie theater.
There are 175 girls taking the role of Juliet Hummer, and Kate Winslet is just one of them.
One of the screenwriters, Fran Welsh, searched the local high school to find someone like Pauline Parker himself, and didn't find Mel until two weeks before the filming started.
The diary fragments read in the voiceover of the film are all taken from the real diary of Pauline Parker.
Almost all the scenes that appear in the film are real scenes of the incident. According to director Peter Jackson, when the film crew reached the dirt road where the murder took place, there was a grotesque silence on the scene: the bird stopped singing and everything seemed to be wrong. So they moved about two hundred yards to film this scene.
At the time of the incident, Pauline was 15 years old and Juliet was 17 years old.
