How do movies/TV shows film large crowds?

Well folks, you know how in movies and TV shows, they often have these massive crowd scenes that make you go "woah, how'd they do that?" Well, buckle up buttercup, because I've got the answer for you! They use a mix of real people, extras, and something called CGI to create these epic crowd scenes. It's pretty much like cooking a crowd stew - a pinch of real people, a dollop of extras, and a whole lot of CGI magic. So next time you watch a movie and see a huge crowd, give a little nod to those hardworking CGI wizards, they’re really the unsung heroes here!
