The original creators of it are, not pleased.

Zucker: Pat, Mike and I wrote a script for Naked Gun 4, and we heard Jon Gonda at Paramount had read the script and laughed all the way through it. But somewhere along the line, they decided not to go with Pat and Mike and me. So that’s when they got Seth MacFarlane, and he has Akiva Schaffer directing Liam Neeson. I was never able to meet with Seth.
Proft: I’m not happy — and there’s a story with it. But I’m not pleased. It may come out and may be great — and good for that — but I sure as fuck should be writing it. I should have done this one.
Zucker: About four years ago, Pat and I had one meeting over at Paramount with the then-head of production there. It was a woman who complained about some joke that Pat and I wrote about a police officer having to adjust her Kevlar vest or have a breast reduction or something. It’s just a stupid, mild joke, but that was too much for them. So I can’t even imagine how they’re limiting whoever does Naked Gun 4, if they’re that frightened. We’re not involved, and we’ve repurposed what was going to be Naked Gun 4 — as we called it, Counterintelijence, spelled with one L and a J — and we’re going to go out with that one.
Proft: We’ve been totally blocked out of it. The unfortunate part of it is that Paramount owns it, so they can do what they fucking want. So that’s it.
