In a classroom scene, a teacher mentions that Everest is not Earth's highest geographical point. She asks what the actual highest point is, and the bell rings. The answer is Mt. Chimborazo in Ecuador, which is the furthest point from the Earth's center, but closer to local sea level than Everest. (The Earth bulges at the equator.) However, as the movie is set in 1962, and the analysis that led to Mt. Chimborazo being described that way was performed recently, it is extraordinarily unlikely that's what the teacher is referring to. Also, by the measurement that lists Mt. Chimborazo is highest, Everest is not 2nd, but 10th. Almost certainly, the reference is to K2, which is a point of contention.

The soundtrack for the new "Hairspray" features a rendition of all of the "original" Tracys (Ricki Lake from the first film, Marissa Jaret Winokur from the Broadway cast, and Nikki Blonsky from this film) singing "Mama, I'm A Big Girl Now". Harvey Fierstein appears near the end, but he isn't credited.

The character played by Sonny Bono in the original film does not appear in this film, but the part was the husband of the Michelle Pfeiffer character. Pfeiffer previously appeared in Les sorcières d'Eastwick (1987) with Bono's first wife, Cher.

Four songs were written for the film, but didn't make the final cut: "I Can Wait" (the only one filmed, available on Special Edition DVD), "Mrs. Von Tussle Says" (meant to replace Miss Baltimore Crabs), "Save Your Applause 'Till The End" (Velma follows Tracy around, complaining), and "Turn Back The Hands of Time" (Original "Come So Far"). All 4 songs are on the 2-Disc Special Edition Soundtrack.
