A note about the DVD: the audio commentary track is one of the best, a full scene-by-scene from director David Zucker, producer Robert Weiss and uncredited script writer Peter Tilden with trivia galore about the making of the movie.
Followed by two sequels,The Naked Gun 2½: The Smell Of Fear (1991), and Naked Gun 33 1/3: The Final Insult (1994).
