The Nude Bomb (also known as The Return of Maxwell Smart or Maxwell Smart and the Nude Bomb) was a 1980 comedy film based on the television series Get Smart. It starred Don Adams as Maxwell Smart, Agent 86, and was directed by Clive Donner. It was retitled The Return of Maxwell Smart for television so as to avoid any trouble with the censors. In the film, Smart is called back into service in order to stop a terrorist from exploding a bomb that destroys only clothing, thus giving KAOS a global monopoly on being the world's only supplier of clothes!

Adams' cousin Robert Karvelas (Larrabee) is the only other cast member from the television series to return for this film. Dana Elcar plays the Chief in this film (as Edward Platt had died a few years earlier); no reference is made to Barbara Feldon's character from the TV series, Agent 99, or even her marriage to Smart. Sylvia Kristel, at the time well-known for her appearances in the Emmanuelle film series, makes a brief appearance as Agent 34, with actress Andrea Howard playing the Agent 99-type role (as Agent 22) and Vittorio Gassman playing the Blofeld-like villain. Agent 13 was recast as Joey Forman, who played Harry Hoo in the TV series.

Smart's agency, called CONTROL in the TV series, was called PITS in this film, an acronym standing for Provisional Intelligence Tactical Service.

In spite of the title, the film was given a PG rating due to the fact that there was no frontal nudity in the film. There were five times in the film where the bomb was detonated, but in each case the actors covered up their private areas with strategically placed briefcases, guns (Buckingham palace guards) or shown from a waist up position. In one case members of a football team were in a huddle when a bomb detonated revealing bare behinds of some of the players. In the final scene, another bomb explodes rendering the three stars of the film in the nude, but filmed by the backsides from a distance, and then with a "the end" caption covering each of their backsides.

The film was a box office disappointment. Nearly a decade later another revival film was produced, this time for TV, on ABC. Get Smart, Again! would feature most of the surviving original cast members and ignored the existence of The Nude Bomb for continuity purposes.

In the Freaks and Geeks episode "Tricks and Treats", Sam and his friends announce their plans to skip trick-or-treating on Halloween in order to watch The Nude Bomb at the local theater instead.

An unknown terrorist has developed a new type of bomb that will destroy clothing, but leave people unharmed. Agent Maxwell Smart (this time without Chief, 99, or Hymie) is taken out of retirement and sent back into the field to track down who this madman is and put a stop to his plans.
