During the detention scene the students in the background are all dressed like the cast of The Breakfast Club (Ally Sheedy, Molly Ringwald, Emilo Estevez, Anthony Michael Hall and Judd Nelson).
During the Prom, a version of Simple Minds song, 'Don't You (Forget About Me)' is played. The song was previously used in John Hughes's 1980s classic, Breakfast Club (1985), which also starred actress Molly Ringwald (who plays Mrs. Flynn is this film).
