In an interview with the Hero Complex, director Colin Trevorrow gave away an interesting spoiler.

He told the pop culture website that the T-Rex that will feature in Jurassic World will be the original one, from 22 years ago.

"The T. rex in this movie is the same T. rex from 'Jurassic Park... She's been on the island for 22 years," he said. She's still alive. She's a little older, and she's angry."

Trevorrow also humorously revealed that the T-Rex will be "having a bit of Burt Lancaster-thing going on" to SlashFilm.

Previously, a report flirts with the exciting possibility of a battle between the T-Rex and Indominus Rex in Jurassic World.

Movie Pilot engages the prospect of the former antagonist of the Jurassic Park movies going up against the new hybrid beast in order to claim his throne in the dino kingdom. This does sound like a credible probability. In the most recently released TV spot for the film, it is revealed that the Indominus Rex is not just killing out of necessity but for sport, and a bunch of other dinosaurs are seen dead strewn across the park. This means the Indominus Rex might be trying to assert its dominance, which might not go down well with the former terror of the park, the T-Rex.

Enstars had previously suspected that the T-Rex might play for the good side this time, might have to do with the fact that it was revealed earlier that most of the known dinosaurs on the park will be tame in someway and the new hybrid dinosaur will throw things out of control. This could mean that the T-Rex will help tackle the antagonist force.

On the other hand, as it is believed that part of the DNA of the Indominus Rex will be drawn from the T-Rex, and it will share some of the main characteristics of the carnivore, the T-Rex might relate to the new beast. It might also trigger the dark side of the monster.

Jurassic World stars Chris Pratt, Bryce Dallas Howard, Jake Johnson, Vincent D'Onofrio, Irrfan Khan, and Ty Simpkins.

The Jurassic Park films are based on Michael Crichton's series of novels about pre-historic beasts being revived by revolutionary gene technology. Frank Marshall and Pat Crowley are co-producing the film alongside Steven Spielberg, who directed the first two installments in the franchise.

The film will hit theaters on June 12, 2015.
