Tough to say how it maps but with cinema, you have so many different skill sets needed for every single film. Costumes, builders for sets, audio engineers, the crews, the caterers, location scouts, composers, etc.

In live theater it would be mostly actors, some one time set and costume work, and some recurring support staff.

But then again, there are probably more theaters and theater production by volume.

Fair point, but that's hardly applicable to the llm metaphor. If you're ok with shit work you can just run a program.
