The One Jurassic Park Scene Its Writer Thought Would Be Impossible To Shoot

Although screenwriter David Koepp had several writing credits (Bad Influence, Toy Soldiers, Death Becomes Her) to his name before Jurassic Park, he turned 30 just two days before the dinosaur blockbuster’s release. In other words, he was still wet behind the ears during his first collaboration with Steven Spielberg. Further complicating matters, he was being asked to write the kinds of sequences that had never been credibly executed before, leaving all kinds of uncertainty about what was even possible.

“I wrote a line in one of my first drafts that said ‘The T-Rex bursts out of the trees, chases down the Gallimimus, and devours it in a cloud of dust and blood,’” he told Collider in a recent interview covering many of his career highlights. “I thought, ‘Well, I love that line, and I’d love to see that.’ But I asked Steven, ‘This seems impossible to me, should I take it out? Should I do it another way? What are my limitations?’


Far more experienced than Koepp—and well aware of the technological advances taking place behind-the-scenes—Spielberg made it clear that anything was possible. “He said, ‘Your imagination, that’s the only limit you have. We’ll figure it out.’ But I knew that the real challenge was running. In the movies, if you see a dinosaur and his feet are in the shot it’s probably a puppet or one of Stan Winston’s creations. If you see the legs and it walks, that’s CG, but… nobody knew if it would work or not.”

Fortunately, everything worked out okay and Jurassic Park became the most successful film of all-time—until Titanic took its place four years later. To see those 1993 dinosaurs in action, check out the Jurassic Park clip below.
