4 Dick Summers: that was all the encouragement I needed. I finally got into the film business iท the 70s. Stanley Kubrick had amazed everybody with his beautiful film 2001: A Space Odyssey and I| found myself working on a similar film for a young guy called George Lucas. He kept talking about robots, or swords made out of light, and superfast spaceships, and I kept saying, "Sure, George, but how are we going to make it?" Well, in the end we found a way and Star Wars was a massive blockbuster. We made two more Star Wars films, and I had a great time working on the Indiana Jones movies, but then along came Jurassic Park in 1993 and that changed everything. Snesial Efecls SUPERVISOR A long time ago in a galaxy far, far away . people used to believe whatever they saw with their own eyes. But do you really believe a man can fly? Do you believe aliens are invading Earth or that an evil empire will destroy freedom across the บniverse? For the makers of films like Superman, Independence Day and Star Wars, their mission is to make you believe and that's when they come to someone like me. Over the years, I've travelled through time, breathed life back into dinosaurs and blown up entire planets. Today, I work at Industrial Light & Magic, but my interest in special effects goes back to my childho0od. I remember seeing the alien in The War Uf The Worlds zap some soldiers with a ray gun and I thought 1o myself, "| want to do that. My father had a home movie Camera and I filmed my brother pretending to be a soldier. Then filmed some fireworks exploding. My mum went crazZy When she saw it, but my dad thought it was really funny and Computer animation had been around for a long time, but now we Could make any kind of creature we wanted. Suddenly, it seemed like every film had to have CGI (computer generated imaging) and I think some people forgot that films still need imagination. I enjoy films like The Lord of the Rings trilogy because they've got drama and emotion as well as great Special effects, but my kids like computer animated films like Shrek. Sometimes I try to imagine what kind of films they'|| be watching when they're older, but then look back at how far we've already come. Who could have dreamed any of this Would really happen?
