Terminator 2: Judgment Day is a 1991 American science fiction action film, the second installment of the Terminator franchise and the sequel to The Terminator (1984). Directed by James Cameron and written by Cameron and William Wisher, Jr., it stars Arnold Schwarzenegger, Linda Hamilton, Robert Patrick, and Edward Furlong. Terminator 2 follows Sarah Connor (Hamilton) and her son John (Furlong) as they are pursued by a new, more advanced Terminator, the liquid metal, shapeshifting T-1000 (Patrick), sent back in time to kill John and prevent him from becoming the leader of the human Resistance against the machines. An older, less advanced Terminator (Schwarzenegger) is also sent back in time to protect John.After a troubled pre-production characterized by legal disputes, Mario Kassar of Carolco Pictures emerged with the franchise's property rights in early 1990. This paved the way for the completion of the screenplay by the Cameron-led production team, and the October 1990 start of a shorter-than-originally-planned 186-day filming schedule. The production of Terminator 2 required an unprecedented budget of more than $94 million (1991 dollars), much of which was spent on filming and special effects. The film was released on July 3, 1991, in time for the U.S. Fourth of July weekend.
