Suddenly, Kazurinsky went from simply being a store merchant to Cadet Sweetchuck in both that movie, Police Academy 3: Back in Training, and Police Academy 4: Citizens on Patrol.
While he was never really the lead in the movies, can you possibly imagine the Police Academy franchise without him?
Michael Winslow appeared in every Police Academy movie and he also appeared in the series that ran from 1997-1998.
In fact, he would also appear again as a character on Police Academy: The Series but that was only for one episode.
