“I can’t believe they showed the final act!” screamed a worried Film Twitter.

When the Jurassic World: Fallen Kingdom trailer premiered last night, I personally saw many people on social media bemoaning the fact that it had appeared to showcase a major set-piece from the final act. The film seems to be structured around a volcano exploding on Isla Nublar, and that sequence is front and center in the trailer.

But don’t worry, says writer/producer Colin Trevorrow. You ain’t seen nothing yet.

“Everything in the trailer is from the first 57 minutes,” Trevorrow promised today.

From what we gather, the volcano explosion is merely the film’s halfway mark, at which point it’ll shift over to another threat entirely. We can only assume that the threat in the film’s second half will be the much-talked-about Indoraptor, a new hybrid dinosaur that, refreshingly, isn’t even glimpsed at all in the trailer.

J. A. Bayona (A Monster Calls) directed the new installment.

Chris Pratt and Bryce Dallas Howard are returning for the sequel, which also stars Jeff Goldblum, along with Justice Smith, James Cromwell and Toby Jones. Colin Trevorrow, who directed Jurassic World, wrote the script for the sequel with Derek Connolly.

Producers Frank Marshall and Pat Crowley once again join executive producers Steven Spielberg and Trevorrow. Belén Atienza also produced.

“It’s been four years since theme park and luxury resort Jurassic World was destroyed by dinosaurs out of containment. Isla Nublar now sits abandoned by humans while the surviving dinosaurs fend for themselves in the jungles.

When the island’s dormant volcano begins roaring to life, Owen (Chris Pratt) and Claire (Bryce Dallas Howard) mount a campaign to rescue the remaining dinosaurs from this extinction-level event. Owen is driven to find Blue, his lead raptor who’s still missing in the wild, and Claire has grown a respect for these creatures she now makes her mission. Arriving on the unstable island as lava begins raining down, their expedition uncovers a conspiracy that could return our entire planet to a perilous order not seen since prehistoric times.

With all of the wonder, adventure and thrills synonymous with one of the most popular and successful series in cinema history, this all-new motion-picture event sees the return of favorite characters and dinosaurs—along with new breeds more awe-inspiring and terrifying than ever before. Welcome to Jurassic World: Fallen Kingdom.“
