Did You Know?


Actor Min-jong Kim was originally supposed to reprise his role as Kim Ki-soo (from Athena: Goddess of War (2010-2011) for the second season of Iris (2009). However, his popularity for his most recent show, A Gentleman's Dignity (2012), was still too fresh and fans were not ready to see him return as the North Korean escapee. Ki-soo's part in the script was changed to a new character, named Yoo Joong-won. The part went to Beom-su Lee. See more »

Wikipedia gives the following information: "Iris is a South Korean espionage television drama series broadcast by KBS in 2009. With a budget in excess of 20 billion won (17 million USD), it, along with its spin-off Athena: Goddess of War, share the record for the most expensive Korean dramas ever produced. Premiering in October 2009, the series was a critical and commercial success, with an average viewership of over 30% in addition to ranking as the top program consistently every week after its debut. The series also took home many of the highest honors at the 2009 KBS Drama Acting Awards, including Byung-hun Lee winning the top recognition, the Daesang Award. Among other nominations and recognitions, Lee and Tae-hee Kim were also named as one of the best on-screen couples."

My Review In One Breath: This series (20 episodes, 60 minutes each) concerns a National Security System agent who attempts to take down a secret organization. After the introductory opening episodes, the missions are similar to what one would find in the American "24" series (excluding the "real time" element), with agents attempting to stop terrorist attacks with the use of satellites and information support technicians. Of course, this is in the Korean style with some romance and melodrama blended in. Acting is top notch, with Byung-hun Lee in the lead role and a very good supporting cast: Tae-hee Kim (his love interest and fellow agent), Seung-woo Kim (a North Korean agent) and So-yeon Kim (as the gorgeous North Korean sniper). Production values are slick, the scoring is great at times, and the pacing is very fast for a K-drama with plenty of shootouts (a few of which are fantastic) and suspense. Storyline is clichéd but the secret organization is intriguing and represents a brilliant little twist on the North/South Korean conflict. Consequently, the relationships between the characters change significantly in exciting ways and the viewer will have an emotional investment in the protagonists. Highly addictive stuff.
