Police Academy 4: Citizens on Patrol

Police Academy 4: Citizens on Patrol is a 1987 American comedy film. It is the fourth installment in the Police Academy franchise. It was released on April 3, 1987, and is the sequel to Police Academy 3: Back in Training (1986).

A group of Police Academy graduates are sent to train a group of newly recruited civilian officers. The original Police Academy cast reprise their roles in the film. Capt. Thaddeus Harris (G. W. Bailey), not seen since the first installment, returns as the film's nemesis. In Police Academy 2 and 3, Capt./Commandant Ernie Mauser (played by Art Metrano) filled that role, but Metrano asked to be replaced for the remainder of the series after filming the third film. This was the last Police Academy film to feature Steve Guttenberg as Carey Mahoney. This film also stars a young David Spade in his feature film debut, as well as featuring a brief appearance from pro skateboarder Tony Hawk as Spade's double in a skateboarding scene. The film was a commercial success, but was panned by film critics. It was followed by Police Academy 5: Assignment Miami Beach (1988).
