The premiere of the movie was held in Minnesota, where the movie was filmed. The entire audience was given Betty Doll masks, like the ones the girls used to rob the bank in the movie.
The movie is only 73 minutes long, with two minutes of "where are they now?" and six minutes of credits for a running time of 81 minutes.
Uncredited writer Lona Williams based Cleo's obsession with Conan O'Brien on herself. Williams admits to admiring O'Brien while he was a writer on The Simpsons (1989) and she was an assistant to the producers.
Sugar & Spice was supposed to be a black comedy about murdering for money, but the producers feared it would be too similar to Jawbreaker (1999), another teen black comedy, so the screenwriter re-wrote the script to what it is now. Mena Suvari commented, "Even though it doesn't have murder its still influenced by Heathers (1988)."
References are made to the films Backdraft (1991) and Scream (1996), both staring W. Earl Brown, who plays the Terminator in this film. Marley Shelton (Diane) appeared in Scream 4.
