I'm sure there's plenty of those making a mess of things, but taking time in the writing process, getting input from relevant parties, and doing as much preparation as possible cuts out a myriad of problems.

Studio got a product placement deal? Great, let's integrate that into the story long before filming even begins so it feels natural.

Director doesn't know if he wants plot point A to happen or not? Good thing he heard about that while the movie was just a script instead of having him decide with dozens of people on set.

I'm sure there are uncontrollable, unforeseeable problems that will come up in any production. There is no reason to exacerbate those by being willfully unprepared. An ounce of prevention is worth a pound of cure but it seems like film studios reliably hamper the "prevention" part to shave a few weeks off on prep time and end up losing more time or huge piles of money because of it.
