Most writers would have felt the need to document how Conan went from mercenary to king. And they would have felt the need to document how Conan went from Cimmeria to civilization. But not REH. That's just not how he rolled. Maybe that's why no REH has ever been successfully translated to the screen, and why screenwriters are apparently dumbfounded by his work and unwilling to even try. They're simply not capable of thinking like him. They're stuck within their "safe" cliches of how a narrative is supposed to be structured.
Correct. Didn't REH write to someone (forgot whether it was Lovecraft or an editor at Weird Tales) that his Conan stories just flowed from his gray matter in no chronological order in the Hyborian timeline? He just wrote the stories as if Conan was relating them to him. Looking through some of his drafts like Red Nails too, I don't think Howard ever thought them out carefully. To me, it feels as if he just got a vague idea of what was going to happen, penned it down, then expanded on the details. It's like a reckless raging bull exploding on to the arena, goring anything in its way, before finally calming down and taking time to check the audience out
