The upcoming fourth installment to the 'Jurassic Park' series of films, entitled 'Jurassic World', has been slated for a June 12, 2015 release date. Beyond that, a new full-length trailer has been set up for its debut during the football matches on Thanksgiving Day.

However, for fans too eager to wait, there's already a promotional video clip that has been released by the producers of the film.

Stepping back into the first movie released in 1993, fans saw that John's Hammond's endeavor to bring back the dinosaurs on Isla Nublar fails miserably. Hence, it was decided that Isla Nublar would be converted into a theme park wherein humans would be able to relate to prehistoric creatures.

Eventually, the park was renamed 'Jurassic World', which is at the center of the upcoming film. In the fourth installment of the movie, fans will see people traveling among dinosaurs, which resemble ostriches, on exclusive vehicles that appear to be orbital and high-tech.

The script for 'Jurassic Park 4' has been written by director Colin Trevorrow along with Derek Connolly. It offers a quick look at Spielberg's original film with a view to refresh the fans' memory about the fate of the dinosaurs in the movie.

Christ Pratt, who also featured in 'Guardians of the Galaxy', will portray the lead role in 'Jurassic Park 4'. He will be seen as an employee of the theme park, but will evidently play a crucial role in the happening that develop.

The 'Jurassic World' is a vast expanse and requires a large number of visitors to earn the revenue needed to sustain it. In the clip, a coworker (Bryce Dallas Howard) is seen throwing a concerned look at Pratt's character from the control room after something unforeseen happens.

Although the trailer does not offer much to the fans, they can of course satiate their thirst for 'Jurassic Park' when the film releases next year.
