I'm sorry but those pictures of Bennett and of all those other depictions of Conan that seem one step removed from Frazetta don't work for me. He was a great artist and I respect what he did, but like in any "heroic art" things are made larger than life. There's a reason Charles Atlas was used as the model for statues of George Washington among others, Washington was not that big ... but it makes for an awesome image.
I love the Conan books, heck, I'm reading through the REH canon right now for the umpteenth time. Jason strikes me as much closer to what I imagined Conan as in my head. Jason's voice matches the "deep rumble of millstones" voice Conan should have. He's big, but still believable as a man who grew up on the steppes rock climbing, horseback riding, sword swinging and practicing archery. Conan's built, but not that big, he is dwarfed by other people in the books both by REH and subsequent authors.
We are all entitled to what we think Conan "should" be. But at this point I'm happy with what I'm seeing. I hate to put myself into my posts but I am a martial artist, with 25 years of experience (I started at 5, I'm not that old) and I teach Karate. As a lifelong physical culturist there's a huge difference between functional muscle and muscle for looks. There are just certain looks and builds that look more functional fit but still are impressive, and truth be told Arnold's form when using the sword showed many deficiencies from my standpoint. But again, I'm coming from a Japanese slant where I learned to use the sword in Kendo class.
