21 Jump Street is known as the TV series that launched Johnny Depp’s career, but it also provided a LOT of guest star roles for actors who would go onto bigger things, including Brad Pitt, Rosie Perez, Pauly Shore, Peter Berg, Gregory Itzin, Thomas Haden Church, Diedrich Bader, Jason Priestley, Peri Gilpin and Christopher Titus. One of the most notable budding young celebrities on the show was Vince Vaughn, who made one of his very first acting appearances at the age of 19 as a high school student.
