Police Academy 2: Their First Assignment (1985) has the misfit peace officers, recently graduated from the academy, hitting the streets of a crime-ridden city to clean it up...in their own inimitable way. Steve Guttenberg, Bubba Smith, and human sound box Michael Winslow star. Next, the zany grads head back to the alma mater in "Police Academy 3: Back in Training" (1986) to help line up new recruits in the third slapstick comedy. George Gaynes, Bobcat Goldthwait co-star. Then, "Police Academy 4: Citizens on Patrol" (1987) again features the fatheaded flatfoots, and this time they're trying to set up a town watch with neighborhood knuckleheads even more hapless than they are! Sharon Stone and David Spade join the cast. Two-disc set also includes the original "Police Academy."
