There are some incredible animatronic and CGI dinosaurs in J.A. Bayona’s Jurassic World: Fallen Kingdom, made possible by the team of practical dinosaurs creators under the supervision of Neal Scanlan and the visual effects artists at Industrial Light & Magic (ILM) and several partner studios. But when you have things like CGI dinosaurs and other effects in your movie that need to be added later, you also often need ways for actors to perform with something on set. That’s where an ingenuous mix of methods came in handy to make the blockbuster film -- from the animatronics themselves, to more unconventional stand-ins like cat litter, inflatable dinosaurs, and even a roller coaster track.
In Fallen Kingdom’s first act, former park operator and now dinosaur freedom campaigner Claire Dearing (Bryce Dallas Howard) and her colleague Franklin (Justice Smith) find themselves catapulted inside a gyrosphere over the edge of a cliff on Isla Nublar -- its volcano erupting -- and into the sea. For a stunt like that, actors might normally be filmed against bluescreen and composited into the final scene. But Bayona wanted to see real emotion (read: fear) on the actors’ faces. That would only be possible by replicating a real leap off the cliff.
