The Storm Warriors (simplified Chinese: 风云II; traditional Chinese: 風雲II; pinyin: Fēng Yśn II; Jyutping: Fung1 Wan4 II) is a 2009 Hong Kong film produced and directed by the Pang brothers. It is the second live-action film adaptation of artist Ma Wing-shing's manhua series Fung Wan, following the 1998 film The Storm Riders. The Storm Warriors is based on Fung Wan's Japanese Invasion story arc The Death Battle. Ekin Cheng and Aaron Kwok respectively reprise their roles as Wind and Cloud, who this time find themselves up against Lord Godless (Simon Yam), a ruthless Japanese warlord bent on invading China. The film is a co-production between Universe Entertainment and Sil-Metropole Organisation. A sequel to The Storm Riders was first announced in March 2008 after Universe gained rights to the Fung Wan franchise from former film distributor Golden Harvest. The Pangs aimed on creating a big-budgeted film involving visual effects and stated that The Storm Warriors would not be a direct sequel to its 1998 predecessor. Principal photography for The Storm Warriors began in April 2008 and ended in July; filming took place in three studios located in Bangkok, Thailand. The film is notable for being the first Chinese language film shot in bluescreen. During post-production, effects artists worked on scenes involving computer-generated imagery, focusing on the film's setting and backgrounds.
