The first Hong Kong movie to be recorded in Dolby Digital Surround EX.
The film was originally meant to be Jing Wong's take on the "Tekken" video game. However, Wong did not have permission from Namco to use the "Tekken" name and even at the end of the film, it states that the film is not based on or related to any of the "Tekken" video games and is not licensed by Namco Limited. Yet, Nova is modeled after Jin Kazama, Iron Surfer is modeled after Hwoarang, Iron Surfer's opponent in his first fight is modeled after Bryan Fury, Nova's dad is modeled after Kazuya Mishima and Dark 21 is apparently modeled after Heihachi Mishima (even though it is clear Dark 21 and Nova's father are not related in the film).
