The animated opening sequence actually pays homage to many famous cover arts of the Fung Wen comics which the movie Storm Warriors was based on. Examples are: Evil Wind sitting in front of his Blizzard Blade(Issue#85) Lord Godless bursting in the town gate (Issue#79), Cloud picking the one true Ulimate Sword from the countless Ultimate Swords in the Sword Sacrificial Event(Issue#46), Evil Wind facing behind with the Dragon Spine tied to his back while holding his broken Blizzard Blade(Issue#109), etc.
Both Ekin Cheng and Kenny Ho have played Hero Hua, the protagonist of another Ma Wing-shing comic "Chinese Hero: Tales of the Blood Sword". Cheng starred in the 1999 film while Kenny Ho played the character in the 1990 television series.
Adapted from the manhua series "Fung Wan" by Ma Wing Shing, specifically Fung Wan's Japanese Invasion story arc The Death Battle.
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.
