Computers have revolutionized our visual effects to the point that literally anything you can visually imagine can be made possible in a movie or television show. And with those computer effects improving all the time, it's getting harder and harder to knock the way they look. But smart filmmakers know practical effects still have a place in the industry, and use computers to enhance the raw material of their practical effects. Looking back at the history of pre-CG visual effects, these are a few examples that prove you don't need computers to make things look believable on film. Every single one of these examples still holds up today and each illustrates the ingenuity of filmmakers who just want to bring their visions to life.
