Terminator 2: Judgment Day is a 1991 American science fiction action film co-written, produced, and directed by James Cameron, and starring Arnold Schwarzenegger, Linda Hamilton, Robert Patrick, and Edward Furlong as an adolescent John Connor. It is the sequel to 1984's The Terminator, set ten years later when two machines are sent back in time from the future to protect or assassinate John.
Ideas of the film's plot emerged during the writing stages of The Terminator, but was shelved due to budget and story constraints. After the success of the first film and the technological breakthroughs of The Abyss proved that T2 was reasonable to produce, filming began in October 1990 in California. Budgeted at $94 million, it was the most expensive film ever produced at the time, which enabled the innovative use of computer-generated imagery (CGI).
Terminator 2: Judgment Day was released on June 3, 1991 in the United States to critical acclaim, eventually winning four Academy Awards. Much of the praise went to its groundbreaking visual effects and the actors' solid performances. Like its predecessor, it is often considered one of the best science fiction and action films of all time as well as one of the best sequels of all time. The film was also a blockbuster, earning nearly $520 million in the worldwide box office to become the highest-grossing film of the year.
