It’s no secret that during filming a devastating hurricane hit Kaua’i Island, Hawaii, and forced the cast and crew to take shelter for a few days until it subsided.
The elements didn’t just interrupt filming, but also played a key part in the crew struggling to get their animatronic T-Rex to work as the rain kept causing the robot to malfunction.
The precipitation also soaked the animatronic’s ‘skin’ and caused the T-Rex’s head to droop and shake due to the additional weight – a nightmare for those operating it during key scenes such as the iconic attack on the jeeps sequence.
10. The joke that made the final cut
Mr DNA – the animated character that explained how dinosaurs were genetically engineered in a child-friendly way – was another part of Jurassic Park that almost never saw the light of day.
Screenwriter David Koepp told Entertainment Weekly that the character originally started out as a joke between himself and Spielberg, but eventually seemed like the most logical way to discuss dinosaur DNA extraction from mosquitoes.
He quipped: “I remember Steven and I were wrestling with that very issue, about the DNA, and one of us said, ‘What are we supposed to do? Have a little animated character called Mr DNA?’ And the other one said, ‘Yes! That’s exactly what we’re going to do!'”

11. Toilet humour is no joke for Laura Dern
Laura Dern, who played Dr Ellie Sattler, undergoes a transformation from scientist to all-action hero throughout her Jurassic Park arc, and has been lauded for her badass portrayal of the character ever since.
Unfortunately for Dern, she is still only seen by many kids as the “the girl who put her hand in the dinosaur poo” – according to quotes carried by Moviefone – as Sattler looked to get to the bottom of one sick Triceratops’ illness.
Children apparently refuse to shake her hand to this day too, as they don’t believe she’s ever washed it. That’s the first and last time Dern has put her hand in poop then, and with good reason.
12. Feathers are still a no-go
Feathered dinosaurs have been a topic of hot conversation in the scientific world, with plenty of archaeologists now believing that some were covered in plumage.
Back in 1993, such evidence wasn’t yet popularly accepted and resulted in Spielberg rejecting suggestions that he blanket Jurassic Park’s reptiles in feathers.
That was in spite of on-set dinosaur expert Dr ‘Jack’ Horner – the real-life inspiration behind Dr Alan Grant – pushing Spielberg to do so. The director felt that scaly dinosaurs would be scarier than their feathery counterparts.
13. The coolest Easter egg in Jurassic Park
The other main dinosaur stars of Jurassic Park – the velociraptors – are present during the geekiest Easter egg moment in the entire flick.
During one climactic scene when the cast try to escape via a ceiling duct, one velociraptor stands in front of a projection of a repeating sequence of the letters A, C, T and G.
The letters stand for the amino acids adenine, cytosine, thymine and guanine – the four base proteins that make up DNA.
