Director Dante Lam explained that the title of the film originates from the traditional fire dragon dance that Hong Kong residents used to practice to drive off pestilence and that he believes that there is pestilence in every human's soul that must be beaten out. To prepare for the action scenes, Leon Lai prepared for these scenes by exercising, jogging and swimming. Richie Jen stated that Lam wanted him to "lose weight to add more shadiness to my character. But before making any extra effort, I found myself thinner thanks to the hot weather and so many fighting scenes to shoot." Lai suggested the both Jen and him should sing as a duet for the theme song for the film. Jen stated that he "felt strange. But I liked the song instantly when Mark Lui finished it. We hope the song can lead the audience into a deeper understanding about the movie."

Reception
Perry Lam of Muse magazine writes, 'in designing and executing the action scenes, focuses too much on firepower and body count, and too little on their potential transgressive and transformational power.' Time Out Hong Kong gave the film a rating of three out of six stars noting that it was slightly less memorable than Dante Lam's previous film Beast Stalker. The Montreal Gazette gave a mixed review, saying that the film is "exciting, visually stunning movie, full of action and the bright punchy colours of a Sharp Quattron commercial. Unfortunately, it’s not much more than that." IFC gave a mixed review stating that "Lam's action is innovative and clever, but his approach to the characters is the exact opposite: predictable and obvious. We know these cops from so many previous movies. Not a single thing they do surprises us." The Hollywood Reporter described the film as "the loudest of the year" and "Any real thought about the nature of duty and the law is swept aside for action, action, and more action – which is average for Lam but still superior to most." The Montreal Mirror called the film a disappointment of the Toronto Film Festival, noting "incoherent plotting" and that "Lam obviously has some action chops, but he doesn’t exploit them nearly enough here."
