Cameron devised the premise of the film from a fever dream he experienced during the release of his first film, Piranha II: The Spawning (1982), in Rome, and developed the concept in collaboration with Wisher. He sold the rights to the project to fellow New World Pictures alumna Hurd on the condition that she would produce the film only if he were to direct it; Hurd eventually secured a distribution deal with Orion Pictures, while executive producers John Daly and Derek Gibson of Hemdale Film Corporation were instrumental in setting up the film’s financing and production. Originally approached by Orion for the role of Reese, Schwarzenegger agreed to play the title character after befriending Cameron. Filming, which took place mostly at night on location in Los Angeles, was delayed because of Schwarzenegger’s commitments to Conan the Destroyer (1984), during which Cameron found time to work on the scripts for Rambo: First Blood Part II (1985) and Aliens (1986). The film’s special effects, which included miniatures and stop-motion animation, were created by a team of artists led by Stan Winston and Gene Warren Jr.
