9. The Making of Jurassic Park appears among the merchandise. It was a real book published at the time of the movie's release, written by Don Shay and Jody Duncan. Sadly, it is no longer in print, but you can get an inexpensive used copy online.
11. During the escape from the raptors, the light through the grill shows A, G, C and T, the bases of DNA.
13. B.D. Wong, who plays Dr. Henry Wu, was the only actor from the first film to appear in Jurassic World (2015). Jeff Goldblum, who played Ian Malcolm, will be seen in Fallen Kingdom.
16. Gary Rydstrom won two Oscars for his work on the film's sounds. He developed the sounds of the dinosaurs from various animals and they are all different. He told Vulture that some of the T. rex sounds came from his tiny Jack Russell terrier!
17. Jeff Goldblum is heard saying "Must go faster, must go faster" in Independence Day again. He did not say this again during the filming though. The Independence Day team looped in the dialogue from Jurassic Park.
18. Hammond's memory was kept alive in Jurassic World. Mr. Masrani (Irrfan Khan) built a statue at the new park.
19. Malcolm was also referenced in Jurassic World, since you can spot his book God Creates Dinosaurs in the film.
20. While it is true that many of the dinosaurs in the original film are not realistic at all compared to what scientists believe their real-world counterparts looked like, you could theorize that InGen created the dinosaurs in their own image. After all, in Jurassic World, we see them create their own dinosaur from scratch.
21. Velociraptor is actually Latin for "swift seizer," not "Bird of Prey." Deinonychus is Greek for "terrible" and "claw."
22. The T. rex lived 68 to 66 million years ago, while the Velociraptor lived much earlier, between 75 and 71 million years ago. So, there is no way they would have interacted together.
23. Gary Rydstrom also explained to Vulture that the Dilophosaurus sound came from a swan. "Swans make a cute hooting sound, so the cute version of the Dilophosaurus sounds like a swan, for the most part," he told Vulture. "Part of the fun of doing these kind of jobs is that I had no idea what a swan sounded like before!"
24. Harrison Ford was offered the role of Alan Grant, but turned Spielberg down. He had just worked with Spielberg on Indiana Jones and the Last Crusade, after all. Spielberg let the information slip during a Raiders of the Lost Ark screening in 2011.
25. Another cool sound fact: Rydstrom told Vulture that the sounds of the baby Raptor actually came from baby animals, but things change once Grant realizes the baby is a Raptor.
"That's exactly right; as soon as he asks, 'What kind of dinosaur is this?' you start hearing these raspier baby owl sounds," Rydstrom said. "I already knew what the adult raptor would sound like, that it would have this screechy, raspy sound, so I tried to find a baby animal that has that rasp in it."
