In 1993, Steven Spielberg’s 'Jurassic Park' fundamentally changed how Hollywood viewed digital effects. Originally, the dinosaurs were supposed to be created using 'go-motion' (a refined version of stop-motion). However, a small team at Industrial Light & Magic (ILM) created a digital test of a T-Rex skeleton running. When Spielberg saw it, he was so impressed that he pivoted to CGI for all the wide-range movement shots. Despite its reputation for digital wizardry, the film only contains 14 minutes of dinosaur footage, and of that, only 6 minutes are CGI; the rest are massive animatronics built by Stan Winston. This seamless blend of practical and digital effects was so convincing that George Lucas reportedly realized during a screening that the technology finally existed to make his Star Wars prequels, signaling a new era for big-budget filmmaking.
