It manage to be better than the TV show that it was based upon and has some great sight gags. Probably the best police show parody film made and Leslie Nielsen's best comedic role. Good supporting cast too and worth seeing only for the scene of Ricardo Montalban becoming flat as a pancake.
'Naked Gun' is certainly of its time, and much of it has aged rather poorly. The slapstick won't be for everyone and one sees the punchlines coming from a mile off (although this is also part of the film's appeal). However, there are some cracking lines and brilliant sequences, and one occasionally feels a little nostalgic for a time when movies delivered so much utter silliness with such a straight face.
After the success of the groundbreaking Airplane!, it is clear that Leslie Nielsen is the cornerstone in Zucker's career, an actor who personifies and channels like no other this style of slapstick comedy. There is a level of candid absurdity all around that elevates this type of humour into something somehow cleverly refined, away from foulness and offense. A film that is also enduring the test of time.
