Inspired by John Carpenter's Halloween (1978) and other science fiction work, Cameron wrote the script for The Terminator (1984) in 1982, which is a thriller about cyborg sent from the future to carry out a lethal mission. Cameron wanted to sell the script so that he could direct the movie. Whilst some film studios expressed interested in the project, many executives were unwilling to let a new and unfamiliar director make the movie. Gale Anne Hurd, a colleague and founder of Pacific Western Productions, to whom Cameron was married from 1984 to 1989, agreed to buy Cameron's screenplay for one dollar, on the condition that Cameron direct the film. Eventually, he convinced the president of Hemdale Pictures to make the film, with Cameron as director and Hurd as a producer. Lance Henriksen, who had starred in Piranha II: The Spawning, was considered for the lead role, but Cameron decided that Arnold Schwarzenegger was more suitable as the cyborg villain due to his bodybuilder appearance. Henriksen was given a smaller role instead. Michael Biehn and Cameron's future wife, Linda Hamilton, also joined the cast. The Terminator was a box office success, exceeding expectations set by Orion Pictures, who thought that the film would be short-lived in theaters. The movie proved popular with audiences and earned over $78 million worldwide, from a budget of $6. 5 million. In 2008, the film was selected for preservation in the United States National Film Registry, being deemed "culturally, historically, or aesthetically significant".
