Answer 1

that depends a lot on how important it is, sometimes it’s just a still picture if you need stuff happening a PowerPoint.

Or if it’s a sci fi movie were they do a lot of stuff with it they might hire a team of real ui designers to work on the UI shown in the movie, then it’s usually vfx heavy.
