Who do you think should play Roland Deschain in the upcoming Dark Tower films/tv series?

My choice is discussed in this article. If you have ever read “The Gunslinger” or any of the Dark Tower® series of books, then you know that Roland Deschain has to be somewhat tall, on the thin side, with a face that looks like stone (think Clint Eastwood in TGTBATU), and have blue bombardier eyes.I swear to all that I hold holy, that if Ron Howard effs this up, he will want to sleep with a nightlight on. I am sooo looking forward to this (currently set for a release date in May of 2013). I need to beg Howard for a bit part in the town of Tull, or later. With my luck, he would cast me as Sheemie or one of the Taheen, but I could live with that. What do you all think for the potential of this?
