Trivia: Although Piper Perabo was able to sing for her character, it was decided that LeAnn Rimes would provide Violet's singing voice, albeit with a deliberate deviation from her natural vocal range. This means that during LeAnn's cameo in the movie, she is effectively duetting with herself.
Trivia: Co-star Melanie Lynskey stated that the behind the scenes of the film was hostile at times. When she was cast the costume designer made the snide comment "Nobody told me there would be girls like you," and the crew would try to change the way she looked with excessive makeup and shapewear clothes. She was also constantly told that she was "not beautiful" by the costume department. This affected her so much that to this day, Lynskey makes herself available to younger castmates for help or advice.
