Don't like the casting. I would prefer they stray from any of the Arnold films(and even some of the comics[the ones with original stories anyway]) and focus more on the literary stuff. That's where the gold is. Ray Stevenson looks like he could be a pretty good Conan, but i don't know. As long as he's not this hulking beast of a guy, he'd be fine. Remember, Conan is also a thief and swift, not just a jacked beast of a warrior.
Then again, i'm not that huge a fan of Conan. I always preferred Solomon Kane(the movie sounds like crap), Bran Mak Morn(Worms of The Earth is where it is, folks) and alot of Howard's non-historical fantasy horror stuff, like his Cthulhu mythos stuff. That said, i'd kill for an adaptation of Valley Of The Worm mixed with Richard Corben's graphic novel adaptation of it called Bloodstar. It would be awesome.
