If you were a child in the 90s then no doubt you had a massive obsession with dinosaurs and if you didn't then you were watching the wrong films. Steven Spielberg's massive blockbuster Jurassic Park, based on Michael Chricton's novel, was the high grossing film ever after it's release. Spielberg offered layer upon layer of dino goodness, that to this day still manages to offer the same action and humor as it did nineteen years ago.
The new installment was set a release date by the studios, aiming to have the film released by June 2014. Whether it was the speed that the studio wanted to roll out the new installment or issues over script, it would seem that it could be a while till we see Isla Nublar again.
