John Woo will direct the comicbook adaptation "Caliber" for Infinitum Nihil, Radical Comics and Lion Rock says Variety.

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

"Caliber" is unlikely to be Woo's next pic due to his commitments to finish his ancient war epic "Red Cliff" and shoot the Chinese Revolution romancer "1949".

He's also committed to a remake of 1969 French crime drama "The Sicilian Clan," and American railroad Chinese laborer story "The Divide".
