When "Jurassic Park" came out in 1993, its use of CGI was years ahead of its time.
In ways, every modern blockbuster can thank "Jurassic Park" for breaking so much new ground.
But making this classic come to life was no easy task.
It involved a lot of creative problem solving, casting sessions, and bidding wars to get everything in the right place at the right time.
Just in time for "Jurassic World," out in theaters on June 12, we've compiled some of the most fascinating facts behind the first "Jurassic Park."
Steven Spielberg was author Michael Crichton's first choice to direct.

Some of the other directors that were considered included Tim Burton ("Edward Scissorhands"), Joe Dante ("Gremlins") and Richard Donner ("Lethal Weapon").
According to EW, there was an intense bidding war and Spielberg, who was "Jurassic Park" author Michael Crichton's first choice to begin with, won the rights.
Spielberg's relationship with Crichton (they had already been developing a film together based on Crichton's book "Cold Case") definitely helped Universal come out on top.
There are only 14 minutes of dinosaur footage in "Jurassic Park."

"Jurassic Park" runs for 127 minutes.
Even fewer minutes were dedicated to CGI dinos.
One of the film's most terrifying moments happened by accident.

During the first T. rex attack, the dinosaur breaks through the van's sunroof, terrifying both Tim (Joseph Mazello) and Lex (Ariana Richards).
It turns out the dino wasn't supposed to break the glass.
"I think the T. rex was only supposed to go down so far, and the Plexiglass was the only thing between the dinosaur and us. It came down too far one time, and it chipped the Plexiglas and broke a tooth." Mazzello told EW.
