By July 1984, Lawrence Gordon had replaced Wizan. With few projects in development, Gordon looked at sequels of Fox's existing properties and came across the "AliensII" treatment. Gordon said he was surprised no one had pursued it already. Production of "The Terminator" was delayed for nine months because star Arnold Schwarzenegger was contractually obligated to film "Conan the Destroyer" (1984). Cameron used the time to develop his treatment, expanding it to ninety pages. He drew ideas from "Mother", one of his story concepts about an alien on a space station involving a power-loader suit. This version was better-received by Fox executives and Gordon, but Cameron also wanted to direct the project.
