What happens in that “one episode of the thing”?

Additional to the other commentators: there is still a lot of handmade visual effects (painting/masking on each frame by frame) costs would explode. as far as I remember “the Hobbit” was partially made in 60fps. While I loved it, the make-up crew had suddenly problems to hide all the glue on the dwarfs beards and skin looked suddenly realistic instead of “Hollywood”.

Here is some random link about that: https://www.forbes.com/sites/johnarcher/2014/12/16/hate-the-hobbit-in-high-frame-rate-you-just-need-to-see-it-again/
