I know what goes into a show. I also know that it’s a team of people, and it’s possible to design, write, even scout for locations way ahead of time. And once your script is pretty much locked in, you can just shift pieces into place. It’s a lot of work. But...a fair amount of jobs are a lot of work, and somehow people manage. He’s had x number of years to prepare, knowing he was taking over. If he doesn’t at least have a notebook full of ‘and then the cybermen infiltrate future-google’ ideas, then he’s not really been doing his job.
I do t know that he doesn’t. I don’t know how much ‘break’ he needs, or if it’s the Beeb playing silly buggers. I do know that burnout after a few years is different after one, and that the job can be done because two chaps have done it in recent years. If you are the BBC Wales prop man, it’s probably sensible to have a draw full of concepts ready to go. It’s how things used to be done.
CGI team? They will have a ton of stuff in folders just waiting to be greenlit and finished, and sent to the render farms at Finsbury Park or wherever.
It’s not the dark arts. Otherwise related Courses at universities would be more like hogwarts meets the Jedi temple, and they aren’t.
