In 1991, 'Terminator 2: Judgment Day' pushed visual effects into a new dimension with the T-1000, a villain made of 'liquid metal.' Directed by James Cameron, the film was the first to use a computer-generated main character that had realistic human movements integrated with a live-action environment. The 'morphing' technology used to transform the T-1000 was groundbreaking, requiring massive computing power for the time. This blockbuster was the most expensive movie ever made at its release, costing roughly $100 million. Its success proved that high-budget digital effects were the future of the industry, leading to a decade of CGI-driven spectacles that defined 90s cinema.
