When the T-Rex comes through the glass roof of the Explorer in the first attack, the glass was not meant to break, producing the noticeably genuine screams from the children.
The T-rex occasionally malfunctioned, due to the rain. Producer Kathleen Kennedy recalls, "The T. rex went into the heebie-jeebies sometimes. Scared the crap out of us. We'd be, like, eating lunch, and all of a sudden a T-rex would come alive. At first we didn't know what was happening, and then we realized it was the rain. You'd hear people start screaming."
The film opened on Friday, June 11, 1993, and broke box office records its first weekend, with $47 million. It eventually went on to make more than $900 million worldwide. David Koepp remembers the day it opened: "I was in New York and I walked to the Ziegfeld [Theatre] to see how it was doing. The guy comes out and announces to the big line, 'Ladies and gentlemen, the 7 o'clock show of Jurassic Park is sold out.' And people go, 'Oooh.' And he goes, 'Also the 10 o'clock show is sold out.' And they went, 'Ooooooh.' 'And also Saturday night's 7 and 10 o'clock shows are also sold out.' And I was like, 'I'm not an expert, but I think this is very good.'"
The Tyrannosaurus' roars were a combination of dog, penguin, tiger, alligator, and elephant sounds.
Shortly after Nedry makes his first appearance in the control room, during his argument with Hammond, you can clearly see the movie Jaws (1975) playing in a small video window on one of Nedry's computer screens. That movie was, of course, directed by Steven Speilberg. |
