What I don't understand is how film crews can work together when they are larger than two pizza teams? And when they want to change something, it's almost like they just do it? Surely they have to file a ticket with the Product Owner first? And why don't they wait until the current sprint is done before doing things that clearly belongs to the next one? Why do the producer run around speaking in precise terms when he…
All the things you're describing -- in the spirit of tickets, sprints, etc. -- do happen. They're called pre-production. It takes years (months if you're lucky) to set up how everything will run on set. Producers have a huge list of actionables (tickets), and there is constant iteration (sprints) of parts of the script, of what the film's visual look will be, the tone, figuring out the budget, the crew, etc. And there are huge differences in responsibility between producer and director. A producer doesn't "run around speaking in precise terms" when that would step on the feet of the director, the cinematographer, etc. That would be micromanaging and unprofessional. The producer does very much stick to "user stories". When film crews want to change something, they don't "just do it". They very much do check in with the director or showrunner.
I suspect you're talking about execution, where everyone does "just do" things. When filming, every minute counts and shit needs to get done. Yes, every single person is tremendously empowered to do what's right, within their remit. But that only works because preproduction already worked out most of the kinks, and they should all basically be on the same page. But even then, things constantly go south. Shots take hours to set up and then turn out to be wrong for an infinite number of reasons. There are endless compromises. And during that process, only one person is in charge -- the director -- because they have to make a ton of decisions to compensate for all the things going wrong. So it's teamwork... but it's also a dictatorship and once the director makes a decision after collecting the input they want you do not argue.
You seem to be under the impression that film production is somehow more individually empowering or trusting than software development. It's not.
