I can also see Westerns getting made again, especially with Anime shows such as Trigun and Cowboy Bebop doing so well. Besides that though, in regards to actors that could pull it off. Clive Owen could, w/ that 5 o'clock shadow, maybe like you mentioned Orlando Bloom, and perhaps Jason Stratham(Transporter Dude), though the last 1 might be a lil awkward.
