It's pointless to throw in the air dozens of flimsy arguments to prove that Marique, Artus, Zym, Galongabunmba -oh crap that one wasn't in Conan 2011 was he? - were supposedly remotely "Howardian" in any sense.
Marique was a very Howardian character, very much in the spirit of characters such as Solome (notice I said "in the spirit of", not a carbon copy). What does that mean, exactly? Well, it means that the goal was to do a pastiche, and to introduce characters, themes, and situations that Conan fans would find familiar but would still be different enough to not be a slavish imitation, and in my opinion the filmakers succeeded, and least to my satisfaction. The whole point in launching the frachise with an origin story rather than a straight up adaptation was to introduce audiences to the character by showing the various apects of him, sort of "Conan greatest hits" story. In the film we get Conan the Pict slayer, Conan the Pirate, Conan the monster slayer, and Conan the Thief, which covers a lot more ground than any individual story, with the exception of The Hour of the Dragon, which is chronologically the last in the series and therefore unfit to launch the franchise (HotD, btw, is written as a greatest hits novel because the intention was to intoduce the character to a brand new audience via a British book publisher). What you don't want to do when writing a pastiche film is introduce actual characters and situations from actual Howard stories, because that poisons the well against future adaptations. Both Conan 82 and The Destroyer liberally pulled enough bits and pieces from the original stories to make it problematic at best to ever adapt these as films of their own. Conan2011 for the most part avoided that pitfall while still delivering a story that was recognizably "Howardian" IMO.
Marique, like Solome (and Tsotha Lanti), is not entirely human and is "naturally gifted" at practicing black magic. Additionally, like both Solome and Tascela, she's beautiful (not accounting for individual taste), and she's more than a bit perverted. That's four points of definate similarity to actual Howard villians. And, like I said that's the whole point: making it familiar without being a slavish imitation.
Khalar Zym? Basically, he'a a ruthless, ambitious warlord. Can anyone actually argue that REH never created villians like this? And, like Strabonus, as well as the plotters in Hour of the Dragon, he's willing to use black sorcery (that he doesn't have full control over) to achieve his goal. And like many Howardian villians such as Zenghi from
Lion of Tiberius and Timour from
Lord of Samarcand, the fatal mistake that proves his undoing is in underestimating and trampling with inpunity upon those he considers to be beneath him. It's a theme that pops up in Howard's stories quite often.
There's plenty of Howardian material to be found in the supporting characters as well, especially when considering the theme of barbarism vs. civilization. Notice how Conan's confrontation with each of Zym's henchmen plays out differently depending on what side of the
barbarism vs. civilization scale they happen to fall? Lucius and Remo, the civilized henchmen, reveal themselves to be snivelling cowards who are all too eager to sell out their associates in order to save their own skin. Ukafa and Akhun, barbarians themselves, must be beaten through brute physical force.
And the women in Conan life? The first we see is Conan's mother herself, a barbarian and a warrior, and she's the kind of woman Conan would have grown up with in his village, the kind of woman that Conan would admire and respect. Then we see the "civilized women", for the most part slaves and harlots, who are soft and weak and helpless, and it's clear that while he enjoys their company a great deal, Conan doesn't respect them. And why should he? That takes us to the most important relationship in the film, the one between Conan and Tamera, and here we have a plot progression that is quite similar to the one in
People of the Black Circle. At the beginning of their relationship she's merely a tool to be used to further his own gains, because he sees her as just another soft and weak product of civilization, little better than the harlots and slave girls he takes to bed, but as the story progresses she earns his respect, and they payoff is when he tells her that she's dressed like a harlot and to wear the armor like a "Cimmerian woman".
There's plenty of other Howardian things in the film as well, little things that may have escaped peoples' attention. The Hyborian lanscape is littered throughout with ruins suggesting older civilizations that have long since collapsed, either by the great cataclysm or overrun with barbarians. The petrified forest scenes were quite effective in this regard.
It's all a big diversion to stray from the subject anyways, and I cited two precise sequences in the movie (the battle in Doom's orgy palace and Osric's speech ) which had an extremly strong Howardian feel to them, much more than in the Destoryer and the 2011 reboot to be honest.
To be honest, I stuggle to find what was "Howardian" about the orgy scene other than the slaying and killing. I can't recall a single Howard story that features an "orgy chamber", nor do I rememeber a Howard story where the villian and his minions engage in canabalism. Giant snakes are a staple of Howard stories, and there is an occasional sorceror or his minion who morphs into animals, but I can't recall a sorceror who morphs into a giant snake. I suppose one could argue that Thulsa Doom is one of the serpent men on Valusia, and that a snake is his true form and the human is the illusion, but this argument really doesn't work either, since he slithered off out of danger after morphing. Either he was a coward or, being a giant snake, he was comppletely "out of it".
As for Osrics speech, it's not surpising that it sounds Howardian. The last part is lifted from
The Mirrors of Tuzun Thune:
There comes, even to kings, the time of great weariness. Then the gold of the throne is brass, the silk of the palace becomes drab. The gems in the diadem sparkle drearily like the ice of the white seas; the speech of men is as the empty rattle of a jester's bell and the feel comes of things unreal; even the sun is copper in the sky, and the breath of the green ocean is no longer fresh.
