!! The film:

* HeyItsThatGuy: Short of a ProductionPosse, the film includes Brie Larson and Johnny Simmons in the cast and Michael Bacall as the scriptwriter; all three were involved with ''ScottPilgrimVersusTheWorld''.
** Deputy Chief [[ParksAndRecreation Ron Swanson]] transfers them to Jump Street, [[Series/ThirtyRock Dr. Spaceman]] moonlights as a high school drama instructor, and [[Series/TheOfficeUS Erin Hannon]] became an AP Chemistry teacher after leaving Dunder Mifflin. Unfortunately they just missed the complete set of NBC Thursday Comedy cameos by not getting anyone from ''Series/{{Community}}'' on board.
** Fugazi's father in RealLife also [[MiamiVice worked undercover]].

*** Many actors appeared on the TV series who became famous later, including ''Creator/BradPitt'', Courtney Thorne-Smith, Peri Gilpin, Jason Priestley, Jada Pinkett-Smith, Bridget Fonda, and more.


!! General:

* TruthInTelevision: Whether or not it was deliberately inspired by the show, using young-looking police officers undercover as high school students has ''actually been done''.
