When George Lucas required unknown special effects for Star Wars, he initiated the creation of a company called Industrial Light & Magic. All of that capability has moved completely inside of a computer the price of an affordable family car. There isn’t a blockbuster that hasn’t required such special editing for location or characters since the 1980’s. It was inevitable that once computer technology had matured enough, the talent would likewise move inside a computer.
