The Naked Gun 2½: The Smell of Fear is a 1991 American crime comedy film. It is the sequel to the 1988 film The Naked Gun: From the Files of Police Squad! and the second (and most commercially successful) installment in the Naked Gun film series. The film stars Leslie Nielsen as the comically bumbling Police Lt. Frank Drebin of Police Squad!. Priscilla Presley plays the role of Jane, with O. J. Simpson as Nordberg and George Kennedy as police captain Ed Hocken. The film also features Robert Goulet (who previously made a "special guest star" appearance on Police Squad!) as the villainous Quentin Hapsburg and Richard Griffiths as renewable fuel advocate Dr. Albert S. Meinheimer (as well as his evil double, Earl Hacker). Zsa Zsa Gabor, Mel Tormé and members of the Chicago Bears have cameo roles.

David Zucker returns from the first entry as director and screenwriter of the film. Jim Abrahams and Jerry Zucker serve as executive producers for the film and receive writing credit due to their contributions to the first entry of the series and the Police Squad! television series. However, neither contributed to the screenplay for the film. The film was a box office success, grossing $192 million against a budget of $23 million. It received mixed reviews from critics, who concluded it to be inferior to its predecessor. A third installment in the series, Naked Gun 33⅓: The Final Insult, was released in 1994.
