Watch a Behind-the-Scenes Reel of the Majestic Special Effects in Jurassic World

Making Jurassic World apparently involved a lot more than fancy CGI dinosaurs: It also required a few adults to crawl around on all fours with kids on their backs.

Industrial Light and Magic just released a visual effects reel that shows how the movie—and all its prehistoric mayhem—came together, with layers of animation and effects. It’s all impressive work, but by far the best part is watching humans doing their best dino walks.
