The yearbook that Melissa Joan Hart uses in the movie is from a Philadelphia-area high school named Plymouth-Whitemarsh. The students' pages shown in the movie are really the teachers' pages in the actual yearbook.
Filming the final scenes of the party meant a chaotic destruction of the house. Directors Deborah Kaplan and Harry Elfont gave the go-ahead to completely trash the place. This involved the cast and crew pulling out drawers, dropping food all over the floor, messing up the carpets, and someone spray painting "This Party Sucked" on the front door. This all happened in one hour.
The Klepto Kid, played by Chris Owen, appears in multiple scenes stealing something: - Some random items from the convenience store when Kenny Fisher makes his introduction. - A small statue that belongs to Molly (the girl hosting the party). - A Loveburger T-shirt when the band is fighting amongst themselves. - A police car when the party is being broken up. - And finally, a gumball machine at the restaurant the morning after the party.
There were characters in the movie called the Crying Drunk Girl (Jennifer Elise Cox) - who has subtitles for everything she says because she is so drunk that none of her speech is understandable - and the Stoned Girl ('Amber Benson') - who is so spaced out on dope that she wanders in and out of a number of scenes - but both were cut in order to secure a PG-13 rating.
Ethan Embry's character, Preston Meyers, confesses to be a big fan of Kurt Vonnegut Jr. at the end of the movie. His yearbook quote, "Beware of all enterprises that require new clothes" by Thoreau, is also featured in Vonnegut's book "Welcome to the Monkey House."
Adam Hann-Byrd was originally cast as William, but after a couple of days of filming was let go and replaced with Charlie Korsmo. One shot of him is left in the film, but he is carrying a ladder and his face is not visible.
Two characters that had their parts cut can be seen in at least two scenes that survived the cutting room floor. Crying Drunk Girl (Jennifer Elise Cox can be seen falling over in the crowd with the foreign exchange student and crowd surfing during the "Paradise City" scene, and Stoned Girl ('Amber Benson') can be seen staring at a banana in the kitchen early on in the movie.

A character makes reference to Velma from Scooby Doo being under-appreciated and hot. The other character who agrees is played by 'Jason Segal'. Jason Segal was dating Linda Cardellini at the time who would go on to play Velma in Scooby-Doo 2: Monsters Unleashed (2004).

Jennifer Love Hewitt gave Ethan Embry a teddy bear full of breath mints for their climactic kissing scene. He says everyone on set knew he spent most of his time smoking pot in his trailer and she wasn't too keen on kissing Embry, who described himself as "a skunk-scented chimney". He said he gladly used the breath mints as they alleviated his cottonmouth.
Melissa Joan Hart was filming Sabrina the Teenage Witch at the same time, so she had to take the small part of Yearbook Girl. She took B12 vitamins to stay energized during the all-night shoots and admits that Jennifer Love Hewitt was skeptical when she offered them to her, because she was convinced they were drugs.
As Amanda is talking to the stoner guys asking about Preston...after she leaves one of them starts talking about Velma from scooby doo and how she was a hip hip lady...the same reference is referred to Martha Washington as slater talks about her in dazed and confused...
