You kind of missed the “and direct actors to play it out” part. If you did all of that, that’s essentially the creator.

... What was the last word in my comment?

The parent is making a philosophical argument. The exact Hollywood definitions aren’t important since there are far many more job roles in film production compared to software development. If you insist though just replace creator with producer in his original argument and it’s the same - you can produce a movie without doing the acting yourself.

And my response is that creation is never, ever, just assigned to a singular person. All work that goes into a work, is acknowledged.

Pretending that your model use doesn't matter, is ignoring all the people's works that are being used to construct it.

If one director or producer went around bragging that the film was all their work, the Actor's Unions and Writer's Unions would tear them to pieces.

You can't pretend only you are the creator. Because it does matter.
