To stay with the 'consumer economy' tone of the film, from beginning to end there are approximately 73 companies who have product placements shown; from logos to actual items ranging in entertainment, electronics, fashion, food, hygiene, and cars. No money was received from all the product placements in the film.
Rachael Leigh Cook, Rosario Dawson, and Tara Reid had to go to a "Band Camp" for two weeks to learn how to play the instruments their characters used in order look correct on screen. However, they did not become proficient to the level that they could play effectively on the soundtrack. The actual music was supplied by studio musicians.
Early in the movie, when Wyatt and Lex, the pilot of the private plane, are about to escape via parachute, Wyatt enters the cockpit and says: "Take the Chevy to the Levy." This is a sly, indirect music reference to Buddy Holly and his tragic early death in a small plane crash. The statement is a lyric from Don McLean's song, "American Pie", a song that expresses his sadness about the accident.
Briefly during the airplane scene, Alexandra Cabot (Missi Pyle) breaks the fourth wall. Her brother, Alexander Cabot (Paulo Costanzo) wonders why she's even on the plane. She replies "Because I was in the comic book" and when he mis-hears her she corrects herself and says "Nothing."
The "Bubbles" in the Mega Records recording studio change from white to yellow during the course of the film. Apparently the techs could not keep the material they were made out of to stay white, so they just went with it.
During the TRL scene, the cardboard cut-outs in the "audience" feature Johnny Depp (2), Gwen Stefani (2), Christina Aguilera (2), Britney Spears, and Matt Damon. Melody defends herself with Britney and Christina, but Carson Daly hits the cut-outs with a baseball bat. Melody eventually clubs Carson with the Matt Damon cut-out and knocks him off the bleachers.
Tara Reid starred as the band's drummer, Melody Valentine. Not knowing how to play drums before they filmed, she needed to learn the basics so she could appear to know what she was doing behind the kit. The producers hired Drew Thomas. He was in such bands as Bold, Into Another, and Youth of Today. Drew went on to play in the band God Fires Man along with members of Errortype:11 and Garrison.
