New 'Jurassic World' Trailer: Prepare to Meet the Scariest, Smartest Dinosaur (Video)

"They're dinosaurs — it's wow enough."

"It's not about control. It's a relationship based on respect."

A new trailer for Jurassic World highlights the problem with wanting to add "wow factor" to something already pretty spectacular and introduces the dinosaur designed to be more trouble than a T. rex. Prepare to meet the scariest, smartest dinosaur to date.

It centers around both Chris Pratt's dino-handler — who understands what the dinos really want, as he explains to Bryce Howard in the trailer — and the Indominus rex, the new dinosaur that turns out to be smarter (and more dangerous) than even its creators believed. Cue mass hysteria and the things Jurassic movies are made of.

Directed by Colin Trevorrow, Jurassic World opens June 12.
