When asked by Collider About the challenge of bringing the dinosaur scale from the screenplay to the screen, “Jurassic Park” co-writer David Koepp (“Stir of Echoes”) recounts how Spielberg taught him never to guess what his mind is. your imagination:
“I wrote a line in one of my early drafts that ‘T. rex burst out of the tree, chased Gallimimus and devoured it in a cloud of dust and blood.” I thought, ‘Wow, I like that line, and I want to see it too.’ But I asked Steven, ‘This seems impossible to me, should I take it out? Should I do it another way? What are my limitations?’ and he said, ‘Your imagination, that’s the only limit you have. We’ll find it.’ “
The last part of Koepp’s quote is why Spielberg is as respected as he is. You will only damage your vision if you don’t try to at least try to reach for the clouds, even if external factors ensure that it is out of your reach.
The special effects industry is in a wildly different place now than it was nearly 30 years ago when “Jurassic Park” was being assembled. I wouldn’t exactly call it easier, but there are certainly more tools for filmmakers. Whether they use them, or even have access to them, is an entirely different story.
