Caliber sets King Arthur firmly into the American Old West, which is rather fitting, since as a location it's nearly as mythical as Camelot. Arthur is given Caliber, a tattooed six-shooter (how do you tattoo a gun?) given to him by the Native Americans. It's no ordinary gun, as it's never loaded with bullets. Only a man with Justice on his side can fire it, at which point it shoots lightning. Accompanying him through the Pacific Northwest are the The Knights of the Round Table, all noble gunslingers, bound by a code of honor to protect the weak and defend the innocent. I guess they have to carry regular guns, though. I can't find an online preview of the comic for you, unfortunately, so we'll just have to hope a Cinematical reader out there can fill us in on the first issue. It certainly has a pretty cover, but I'm not sold on the premise yet.
Variety mentions that Caliber will be unveiled at Comic-Con next week, but it looks like the first issue came out in May 2008. So I'm not sure what exactly is being unveiled, but it will the last bit of news we may have on the project for a while, as Woo has a very full slate. He has a number of projects to complete before he tackles Caliber -- editing part two of Red Cliff, 1949, The Sicilian Clan, and The Divide. The King Arthur trend may have come, gone, and become ready for another resurrection. One with doves flying in slow motion.
