If you think filming is the only skill needed to make a film, may I suggest looking at the very long list of names that appears at the end of the film of which only a few actually do filming? Takes a lot to know what to film, and how to be good at using the tools you have.
Similar is true for a lot of software. Credit list on video games… I don't want to say it "mostly" isn't coders, but only because I've not done an exhaustive study. My guess is the top will either be QA or art.
Artists of all stripes (including audio, animation, cinematographers, lighting, environment, textures, etc,) including tech artists, designers, writers, musicians… the ratio of functionality to look-and-feel is dramatically different than in non-entertainment products, and the labor involved reflects that. It’s a real shame that some of the people that contribute most to what makes a game great are often the first to get dropped when people talk about how the game is made, (but most are perfectly happy to fly under the radar when a bunch of entitled kids start raging about the “lazy devs.” ;)
