Here's a fun piece of trivia: Steven Spielberg was originally going to use stop-motion animation for the dinosaur sequences in Jurassic Park. That's right, one of the most iconic films in the world, a landmark in the evolution of CGI almost ended up looking like Jason and the Argonauts. Thankfully, when the director approached Industrial Light and Magic about adding motion blur to his model raptors, the special effects house managed to convince him that completely computer-generated dinosaurs were the way to go. And the rest, as they say is history. After the break is a nice short film from the Academy of Motion Picture Arts & Sciences that tells the tale from start to finish, and even gives you sneak peeks at the stop-motion test footage and the first batch of CGI proofs of concept.
