In a minute-long movie marvel called The Conjurer, created in 1899, French magician- turned-filmmaker George Méliès one-upped his colleagues in the conjuring trade. He made himself literally disappear, then he made his female assistant disappear. She turned into him. He turned into her. She turned into confetti-all in plain sight. With this 60-second film, special effects had found its first master.
Today's movie magicians have graduated to making entire cities disappear, a stunt pulled off with alarming realism in the 1996 film Independence Day, in which extraterrestrial invaders set out to systematically destroy the world. Despite the increase in scale, special-effects artists still rely on the same visual sleight of hand that early filmmakers practiced. Only the technology has changed.
A unique behind-the-scenes look at how movie-makers use special effects to create memorable, thrilling scenes is in store for viewers in a new film showing at Carnegie Science Center's Rangos Omnimax Theater through June 12.
Special Effects explores the method behind the magic by following the wizardry that goes into blockbuster movies including the Star Wars Trilogy Special Edition, Independence Day, Jumanji and Kazaam.
Carnegie Science Center is one of 18 science museums worldwide showing Special Effects. Produced by NOVA/WGBH Boston and narrated by actor John Lithgow, the film "celebrates 100 years of cinema and the technological achievements that have made special effects a critical part of the entertainment industry today," says the film's award-winning producer, Susanne Simpson. As executive producer of NOVA Large Format Films, Simpson has brought to the screen To The Limit and Stormchasers, both of which were shown at Carnegie Science Center. Special Effects was directed by Ben Burtt, the winner of four Academy Awards for his innovative sound design on Star Wars, E.T.: The Extraterrestrial, Raiders of the Lost Ark and Indiana Jones and the Last Crusade.

QUIZ ANSWERS
1.C. Just before this point in the film Moses parts the Red Sea. This was accomplished by filming water pouring down two sides of a U-shaped tank and then running the film backwards, making the water appear to divide. Keeping the walls of water apart, however, while the Israelites walked through, was much trickier. A slab of JELL-O was sliced in two and filmed at close range as it jiggled. This shot was then combined with live-action footage of the Israelites walking into the distance.
2.C. The real King Kong was an 18-inch-high puppet with a metal skeleton covered with foam rubber and rabbit fur. A technique called "stop motion" brought him to life. Animators posed Kong, exposed a shot, then moved him slightly and exposed another shot. Twenty-four such shots last one second on the screen. Kong's fur was matted by the fingers of his animators when they handled him for each shot, and his fur appears to ripple as a result.
3.B. The Rains Came lavishly created an earthquake, a breaking dam and flood, and a collapsing temple.
4.D. Many movies rely on several different techniques to produce an important effect. For example, Jurassic Park used a mix of animatronics, puppetry and computer animation to create its famous dinosaurs. Similarly, the best-known movie twister ever-in The Wizard of Oz-was created with actual tornado footage when shown in the far distance, a coiling stocking when shown in the middle distance and a large burlap bag emitting a cloud of dust when shown close up.
5.C. In what is one of the most complex special-effects sequences attempted, the massed forces of the Rebel Fleet take on the Death Star at the end of Return of the Jedi. Legend has it that among the hundreds of ships in the shot are a sneaker and a few sticks of gum. Whether or not this rumor is true, it points out a key fact about perception: that we interpret things we see indistinctly in the background when our attention is focused elsewhere. Thus an oblong object in the distance, like a shoe, suggests a spaceship-if there are real-looking spaceships in the foreground.
6.C. The sequence shows the T-1000 morphing into a succession of human forms that it has assumed earlier in the movie. The realism of these transformations is made possible by the ability of computers to take one image and systematically transform-or morph-it into another.
7.D. Toy Story is the first feature film created entirely with "CGI," or computer-generated imagery. Parts of Jurassic Park and Casper have digital characters (dinosaurs and ghosts respectively), but Toy Story has gone all the way, rendering every element with sophisticated mathematical models. Over 800,000 hours of number crunching went into the final film, which works out to more than a week of computer time for every second on the screen.
In Toy Story "Sid the sadistic kid" has precisely 15,977 computer-generated hairs, and a typical tree in the film has 10,000 leaves. Human skin is made of up to 10 separate layers, controlling freckles, blushing, facial hair, oil layer and wrinkles. Human characters started out as skeletal models programmed to move the way real people do; toys had their own unique movements, with 212 animation controls needed for the character Woody, with 58 for his mouth alone.
