Even small budget indie flicks, when filmed in LA, have a ridiculous amount of paperwork and dealing with unions. Which isn't surprising, since it's an established industry there. Spending $1 million for each day of filming is totally achievable. I don't have personal experience with this but I know some people in the industry and have had conversations with them. Was background/extra in a movie. An AI director/producer doesn't have to deal with the human aspect, actor and other people's egos and clashing behavior. There are moments of film gold that are the result of human actor's human personalities, so we'd lose out on that though.
