Industrial Light & Magic, which was later acquired by Lucasfilm and served as the basis for Skywalker Sound, is credited with developing sound effects—the eternally humming lightsaber swoosh is only one. Jurassic Park’s use of computer-generated imagery (CGI) was pioneered by Industrial Life & Magic.
It started the whole movie-franchise thing
Before Star Wars, there weren’t many film tie-ins or cross promotional goods like toys. It was the first time that movie merchandising rights have been proven to be as valuable as the movie itself.
In 1978, Star Wars toys generated over $100 million in sales. Fast forward to 2011, and Star Wars toys have totaled more than $3 billion in sales despite the absence of a new film that year. Anyone who was born after the premiere of Star Wars may recall playing with an action figure of their favorite movie character, whether it’s Obi-Wan Kenobi, Spiderman, Batman, or Ninja Turtles. Watch Netflix’s The Toys That Made Us series to learn more about this; there’s a fantastic Star Wars episode included.
