John Woo is set to direct comic book adaptation Caliber.  The project unveils at next week’s Comic-Con in San Diego.

The film most likely be a three-way co-production of Johnny Depps’s Infinitum Nihil, Barry Levine’s Radical Comics and Lion Rock, the U.S.-based shingle that Woo runs with longstanding partner Terence Chang.

Radical Comics’ hit story sets King Arthur and his knights as 19th century gunslingers in the Pacific Northwest.

“Caliber” is doubtful to be Woo’s next film. He is editing part two of his epic Red Cliff for a January release in Asia and plans to deliver an international version shortly thereafter.
