'Jurassic Park 4' Trailer & Release Date: Mutant D-Rex Revealed in First Teaser?

Jurassic World opens twenty-two years after the events of the last movie, and it will bring back memories from the 90s.

However, fans of the dinosaur saga will have to wait awhile to get a glimpse of the upcoming film, since producers decided to run the first teaser trailer in December instead of November. Despite rumors about the trailer's delay, a source for the Lawyer Herald said, "I just got word that the theatrical trailer has been pushed back to debut with The Hobbit. This is for strategic reasons and not because of any actual delay with getting it ready. Universal is choosing to debut the Fast 7 trailer on Interstellar instead. Whether or not they still choose to debut it online in November, I have no idea."

Fans who are excited to see the new film can expect changes in the park, as the synopsis include a new species of dinosaurs, called Diabolous Rex or D-Rex, which is a monstrous mutant dinosaur that will wreak havoc in the park. The creature is not a newly discovered specie, but rather, it was made specifically to add to the tourist attraction, created from splicing the genes of the Tyrannosaurus Rex, the Velociraptor, a cuttlefish, and a snake.

According to Master Herald, "Jurassic World" is a "new take on the 'Jurassic Park's old setting,' and it looks like it will be a promising flick."

The website also said that a leaked trailer description includes the appearance of Great Whites as food for the sea dinosaurs, and that there are possibilities that the other species can be tamed enough to help control the threat of the D-Rex.

Action is everything to the Jurassic Park films, however, the final scene that fans can look forward to is the possibility of the appearance of original character, Michael Wu. Rumors have it that he might be eaten up by one of the dinosaurs he has created, and let's face it, the appearance of an original character is a cause for celebration.

"Jurassic World" will be released in theaters on June 12, 2015.
