When Pamela Anderson first read the script and saw there was a scene in which Beth would need to perform a scat solo she told director Akiva Schaffer that when she was in 8th grade jazz band playing saxophone she would sing the scat solos which he didn't believe until she did it in front of him and got the job.
Liam Neeson was 72 years old at the time of filming, five years older than Leslie Nielsen was at the time he made his final film appearance as Frank Drebin (aged 67 at the time he filmed Y a-t-il un flic pour sauver Hollywood ? (1994)).
Akiva Schaffer revealed why he wrote only one O.J. Simpson joke in the film, "To be honest, we never wrote another O.J. joke. We just went, 'Yep, that takes care of that,'" Schaffer says. "I didn't know that the joke would kill as hard as it did at our first test screening. If I had known that, then maybe I would've written other jokes. But you want to be respectful of everything that revolves around him, so it's not something I really took glee in. We just had to acknowledge it in a way we thought was not dancing on anybody's misfortunes."
In 2018, David Zucker said he, Jim Abrahams, and Jerry Zucker wrote a script for a fourth film in which Frank Drebin's son was a security guard who gets mixed up with the CIA and is sent on a spy adventure. It would have been a spoof of the "Bourne" and "Mission: Impossible" films as well as the newer Bond films with Daniel Craig. The original title was "The Naked Gun 4: Nordberg Did It," then got changed to "Naked Impossible." According to Zucker, the script was enthusiastically embraced by Paramount production head Jon Gonda. However, in a later meeting, the script was not as well-received by Gonda's boss, who objected to some mild off-color jokes (including one where a woman gets a breast reduction to fit into a Kevlar bulletproof vest). Nothing happened with the project after that, and Zucker only found out about the reboot when he read about it in the press.
Pamela Anderson was offered the role of Tanya in Y a-t-il un flic pour sauver Hollywood ? (1994), but had to turn it down due to scheduling conflicts.
