The full crew list (per IMDB) for any 1929 movie I've found fits entirely on one screen. The full crew list for a current day movie takes many dozens of screens, often well over 1000 people in all. The first 2019 movie I picked has more stunt performers than the top-rated 1929 movie has total cast and crew. I think it's incredible if we're putting 100x as many people to work (some risking serious injury) and only doubling the cost of the end product. Economies of scale are great.
