Ideas for a Conan film were proposed as early as 1970. A concerted effort by executive producer Edward R. Pressman and associate producer Edward Summer to produce the film started in 1975. It took them two years to obtain the film rights, after which they recruited Schwarzenegger for the lead role and Oliver Stone to draft a script. Pressman lacked capital for the endeavor, and in 1979, after having his proposals for investments rejected by the major studios, he sold the project to Dino De Laurentiis. Milius was appointed as director and he rewrote Stone's script. The final screenplay integrated scenes from Howard's stories and from films such as Kwaidan and Seven Samurai.
