To anyone who thought Milius's Conan was "light" (rather than simply not-REH), I recommend A Critical Appreciation of John Milius’s Conan the Barbarian by David C. Smith:
Milius very much wanted to make the movie, and he jumped at the chance to direct it when the opportunity presented itself. He rewrote an original screenplay drafted by Oliver Stone [1] (in which the action takes place in a post-nuclear holocaust future) and set the story firmly in Howard’s own Hyborian Age, and meanwhile brought to the reenvisioned movie the nobility of the samurai bushido code of discipline, duty, and honor and an appreciation of German philosopher Friedrich Nietzsche’s late-Romantic era concept of the übermensch or overman. The synthesis works well even though the idea of Conan as fascist strongman is counter to Howard’s own political sensibilities.
