Arachi: The enlightened female master. "Ara" comes from both "arumdapda," meaning "beautiful," and also "al," referring to an egg, the holy source of life.

Palm-Blast: The masters can concentrate their ch'i energy attained through training on their hands, and blast it from their palms like laser beams. This technique is referred to in Korean as "palm-wind," or "jang-pung."

Inner Strength: The cumulative level of ch'i energy in a martial arts master, gained through ceaseless training in breathing techniques and control of the mind.

Light Skills: The methods of moving one's body light and fast as a gust of wind.

Levitation Techniques: Through the control of the flow of ch'i in their bodies, the masters can propel themselves into the air.

Inviting Corruption: When a martial arts master misuses his ch'i energy, it shuts down the natural flow of ch'i in his body, resulting in disability or even death.

RYOO Seung-wan has stated, "The best thing I have done in my life was not debuting as the director of "Die Bad", but employing Seung-bum as an actor." Director RYOO, who had recognized from the beginning his brother Seung-bum's talent, is the only one who can extract and display to the audience the total sum of what RYOO Seung-bum could show and what he could not show... until now.

For "Arahan", the RYOO brothers are joined by their former collaborator on "No Blood No Tears", the martial arts expert JUNG Doo-hong, who has earned a solid reputation as both martial arts director and actor over the years. Working closely as a team, they have generously shared their expertise in direction, performance and martial arts with one another, putting together detailed visual continuities for the film, six months prior to the commencement of the principal cinematography. The fateful second get-together of these master-hands, upgraded in skill and ever more experienced, is one element that sheds bright light onto the future of the "Arahan" project.

The action sequences of "Arahan" are centered on the innovative combination of realistic bodily action moving at lightening speed, and the recreation of old-style martial arts pushed to the limits of one's imagination. Within the time frame of contemporary Korea, warm and familiar characters encounter boundless fantastic imagination, creating cinematic fun unseen in any other film.

All the film's major actors trained hard to perfect their swordmaship skills and wire action. RYOO Seung-bum and YUN Soy had to perform, among other sequences, a high-speed chase from one skyscraper to another, crashing through windows and jumping across roof-tops, as well as the never-before-attempted underwater ch'i energy duel. The two leads had to train six hours every day for three months to perfect their martial arts and wire action. Not only them, but also the veteran actors who play the Seven Masters, including AHN Sung-ki, BAEK Chan-ki and KIM Young-in, threw themselves into the tough training sessions, so as to capture the authenticity of the tough action sequences.

The filmmakers also employed computer-generated effects which have taken more than six months to complete, to create such fantasy sequences as the firing of the ch'i power and traversing skyscrapers. Perfectly illustrating the moment of Eastern serenity that cuts through the dynamic action and the violent yet harmonious interaction between the push and pull of the swords, these sophisticated special effects are raising high expectations that "Arahan" will showcase powerful, transcendent action sequences never before seen in Korean cinema.
