Talks of a follow-up to The Terminator arose following its release, but its development was stalled because of technical limitations of the vital computer-generated imagery required to realize a liquid metal Terminator, and legal issueswith original producer Hemdale Film Corporation, who controlled half of the franchise rights. In 1990,Carolco Pictures acquired the rights from Hemdale and production immediately began, with Schwarzenegger, Hamilton, and Cameron returning. Principal photography began in October 1990 and lasted until March 1991. Its visual effects saw breakthroughs in computer-generatedimagery, including the first use of natural human motion for a computer-generated character and the first partially computer-generated main character. At the time of its release, with a budget of $94–102 million, Terminator 2: Judgment Day was the most expensivefilm ever made.
