Stone then turned it into a novel, retitled Charade, which found a publisher and was serialized in Redbook magazine, as many novels were at the time. The series caught the attention of the same Hollywood companies that had passed on it earlier. The film rights were quickly sold to producer/director Stanley Donen. Stone then wrote the final shooting script, tailored to Cary Grant and Audrey Hepburn, with Behm receiving story co-credit. Hepburn shot the film in the fall of 1962, immediately after Paris When It Sizzles, which was filmed that summer in a number of the same locations in Paris, but difficulties with the earlier production caused it to be released four months after Charade. When the film was released at Christmas time, 1963, Audrey Hepburn's line, "at any moment we could be assassinated", was dubbed over with "at any moment we could be eliminated" due to the recent assassination of President John F. Kennedy. The dubbed word stood out quite clearly, so official video releases of the film have since restored the original dialogue, though some public domain videos taken from original release prints still carry the redubbed line. At the end of the film, Hepburn lists Grant's aliases, concluding, “I hope we have a lot of boys and we can name them all after you.” In the Criterion Collection's 1999 commentary, Stone laments the fact that the music swells to mask his “best closing line”. Donen tells him he can say it now and get his own back. It is not clear whether they were not aware of the change—on the same commentary, Donen denies the restoration of “assassinated”—or if the soundtrack was altered after the commentary was recorded.

Cary Grant, who turned 58 during filming, was sensitive about the 25-year age difference between Audrey Hepburn (33 at the time of filming) and himself, and was uncomfortable with their romantic interplay. To address his concerns, the filmmakers agreed to add dialogue that has Grant's character comment on
