The first trailer for the upcoming Jurassic World movie has gone online, resulting in wild speculation across the internet about the story and surprises in store.

The movie, which is the fourth film in the Jurassic Park franchise and the first in 14 years, is not due for release until next summer, but is one of the most anticipated movies in recent years, with the trailer being viewed nearly 13 million times in its first 24 hours online.

The trailer makes clear that the film returns to its origins with two children facing the threat of a dinosaur on the loose at the Jurassic World theme park, but this time the threat of one (or more) “hybrid dinosaurs” is going to be faced by Chris Pratt rather than Jeff Goldblum.
