Songs performed by Taran Killam were credited to his character, Jordan Cahill, both in the movie and on the soundtrack.
When her brother asks Jordan's birthday to hack into his cell, Brittany tells him it is 4/1/82. Taran Killam's actual birthday is 1 April 1982.
Jordan Cahill's cell phone is a Palm Treo 600 smartphone.
Although Brittany and her friends are supposed to be in eighth grade (as they attend Lincoln Park Middle School and Natasha says they have four and a half years until they graduate high school), both Danielle Panabaker (Brittany) and Brenda Song (Natasha) were 16 at the time of the film's release.
