The Storm Warriors is based on
Fung Wan, a
manhua series created by Hong Kong artist
Ma Wing-shing in 1984. The film was directed by
Oxide Pang and his brother,
Danny Pang, who served as a co-editor on the 1998 film
The Storm Riders. The film was produced as part of the Pangs' ten-year motion picture deal with Universe Entertainment. A sequel to the 1998 film was first announced in March 2008. Film distributor Universe Entertainment gained rights to produce the film from
Golden Harvest after the latter company's ten-year production rights to the
Fung Wan franchise expired. The film is based on
Fung Wan Japanese Invasion story arc
The Death Battle, which follows Wind and Cloud as they fight against a Japanese warlord. The Pangs have stated that
The Storm Warriors is not a direct sequel to
The Storm Riders, but more of a stand-alone film with a separate storyline. It was announced in April 2008 that the Pangs had changed the film's English title from
The Storm Riders II to
The Storm Warriors in order to avoid copyright conflicts. The name change was made to head off any potential copyright disputes with the comic's current license holder who is no longer associated with the film's financiers.
Casting Ma Wing-shing was very concerned about the film's casting. He was especially adamant of Aaron Kwok and Ekin Cheng reprising their respective roles. Ma also dismissed that the actors might be too old for the film. He commented on the actors and their roles: "My concept of Cloud was someone with a tortured soul, and Aaron resembles the actual comic Cloud more today than he did 11 years ago. He is less baby-faced, and looks more mature and manly now...As for Ekin, he was more carefree in the first movie, but it will be more challenging for him this time around because he has to turn evil."
Filming Aaron Kwok and Ekin Cheng, along with the Pang brothers, executive producer Daniel Lam and the film's crew celebrated production of the film with a traditional Thai blessing ceremony. Filming for
The Storm Warriors began in April 2008 and ended in July 2008.
Principal photography for the film took place entirely in three studios occupying in
Bangkok's Pak-Gret district. Filming consisted mainly of a Thai production crew, as the Pangs decided to shoot the film in Thailand, rather than in their native Hong Kong: "We wanted to shoot the whole film...because we trust them, and because it's probably cheaper than shooting in Hong Kong, even though we have to fly in some of the props and costumes." Members of the media and the film's distributors across Asia were invited to visit the shooting location. They also invited to view a fight scene between leading actors Ekin Cheng and Aaron Kwok as it was being filmed. The Pangs decided not to shoot the film entirely in bluescreen, as it would have gone over budgets and ruined the look of the film. Oxide Pang commented on the film's look: "We decided to make it more realistic-looking, and less like a comic book, but you will instantly know that it is a movie made out of a comic book just by looking at the background." During
post-production, more than 1000
CGI shots involving the film's settings and background were created for the film. == Release ==
