If Hogwarts was real, there would be mandatory CGI classes. Because if not for the visual effects’ wizards, the magic of the silver screen wouldn’t exist. Yet, on the other hand, a wooden magic stick is cheaper than a team of experts with all the necessary equipment. That being said, Harry Potter films cost from $100 to $250 million each. The higher the price, the more revolutionary the effects, which paved the road for a new generation of CGI standards in the industry.
