The CGI Rex matches the animatronic seamlessly, and the shot remains convincing. Because the Rex needs to move at a full-speed lope, this sequence is also CGI. After the paddock attack, for instance, there's a scene in which the T-Rex charges a Jeep driven by Robert Muldoon (Bob Peck). Sequences that show the Rex engaging in full-range motion could only be completed with CGI. Of course, not all T-Rex scenes could be accomplished by practical means. This means that the actors are responding to a highly detailed, fully articulated monster rather than a green screen. The scene holds up remarkably well in 2020, as does its star dinosaur. Surprisingly, many of these paddock shots were accomplished using one of two full-scale animatronic T-Rexes designed by master effects pioneer Stan Winston. Most of the Rex's screen time occurs during a scene in which the animal breaks out of its paddock to assault a pair of Ford Explorers and their human occupants. With its imposing teeth and permanent scowl, the animal oozes character, and carries an eerie resemblance to Dustin Hoffman in Spielberg's Hook. Here's a rundown of some iconic Jurassic Park dinosaurs, along with an explanation of what's practical and what's CGI.Īrguably, the most beloved character in Jurassic Park is not Ian Malcolm (Jeff Goldblum), Ellie Sattler (Laura Dern), or Alan Grant (Sam Neill), but the unnamed T-Rex. Although recent entries in the series have created interest within a younger viewing demographic, some fans of the original have argued that Spielberg's sparing use of CGI makes for a superior viewing experience. With Jurassic World 3 slated for release in 2022, fans of the franchise have cause to revisit the original. Related: Jurassic World 3 Returning To Site B Can Properly End The Franchise

Only when he viewed the impressive results of a CGI T-Rex test run from ILM (Industrial Light & Magic) did Spielberg give serious consideration to using computer-rendered dinosaurs at all. In fact, viewers might be shocked to discover that, despite its 120-minute running time, Jurassic Park carries a mere 6 minutes of CGI work.

Among other discriminating choices, including Spielberg's masterful use of scale framing, one secret to the original film's success is that the director only uses CGI as a last resort. Many viewers have noted that while the original Jurassic Park is 27 years old, the visuals continue to impress, and they're arguably more convincing than recent entries in the franchise.
