The fourth "Jurassic Park" sequel, "Jurassic World", is set to release on June 12, but fans are already trying to get as many details as they can in the meantime.

International Business Times reported that leaked footage from the video has been circulating on the internet for a while. After the first official trailer was presented, fans were able to witness a new hybrid dinosaur and new behemoths that were not featured in the first three films. The second trailer will most likely provide more information about the new hybrid dinosaur, known as Indominus Rex.

One Reddit user uploaded a video which is purportedly the second trailer. In the initial scene of the video, the gyrosphere is shown with the voice-over saying, "Welcome to Jurassic World". The following scene features actor Chris Pratt, saying to Bryce Dallas Howard, "It's like taking a stroll through the woods." There is also a scene of Pratt attempting to pacify a few velociraptor dinosaurs. There were also other scenes that were already shown in the first trailer. The second trailer also hinted that several people will be trapped on the island as the dinosaurs run loose.

Particularly, fans had a clearer view of the Indominus Rex dinosaur. According to a scientist in the film, the new hybrid was made to be bigger than the Tyrannosaurus Rex that caused havoc in the original "Jurassic Park" movies. There is an action scene showing the Indominus Rex trying to escape gunfire from a hovering helicopter. There will also be better views of the giant Mosasaurus, which appeared in the first trailer. A man's voice-over described the Mosasaurus as "shy" and asked the audience to clap their hands when she decides to show herself.

The same IB Times report stated that the video is apparently a collection of scenes that the producers planned to use for the movie ad. The video may not actually the final cut to be officially launched as the second trailer.

Enstarz also reported that the new "Jurassic World" Super Bowl poster was recently revealed, showing the horrific open maw of the Tyrannosaurus Rex.

The upcoming film is based on the novel series written by Michael Crichton, depicting prehistoric creatures that are brought back by state-of-the-art gene technology. Steven Spielberg will be returning as producer, together with Frank Marshall and Pat Crowley. The dinosaurs in the film are made using computer graphics and scale models.
