Well that's the question, now that they've set up the process, how long would it take to repeat it? A month, a week, a day? Can other people pay them to use the process? Can other people copy their process for free? Has filming on Avatar 5 started yet?

On top of that, you're forgetting about AI. How long will it take AI to figure out how to do this process and automate it? Then you just pick a movie as a style guide, tape yourself doing something, and the AI will turn it into an anime instantly.

Whatever the reason Netflix did it, they are now in a position to jump on new technology.
