According to 'Get Smart' writer-producer Leonard Stern, the idea of a "nude bomb" was forced on the writers by the producers. The original idea by the writers - who also wrote the original series - was for the villain to want to control the world by dressing everyone in his designer clothes. The film was supposed to be titled 'The Return of Maxwell Smart' but the producers thought the new title would draw more viewers. Because of many disagreements, the writers were not allowed on the set.
According to Barbara Feldon, she was not asked to reprise her role of 99, but wouldn't have accepted even if she had been.
The high majority of the nude scenes feature only men. This avoided the problem of covering-up a lot of topless female nudity in this PG-rated movie. Ironically, this movie features one female see-through wet t-shirt shot.
Softcore actress Sylvia Kristel plays Agent 34. Ironically, though this movie is titled "The Nude Bomb", Kristel is never seen nude nor even partially naked.
This is the only ever theatrically cinema released 'Get Smart' movie featuring the original Maxwell Smart played by Don Adams.
Joey Forman: The actor who played Hawaiian detective Harry Hoo from the original Get Smart (1965) TV series plays Agent 13.
Bill Dana: As Jonathan Levinson Seigle, a character name which is a parody of Jonathan Livingston Seagull from Jonathan Livingston Seagull (1973).
