KBS2TV behind the scenes filming of "Generation of Youth" (script Chae Seung Dae, director Kim Jung Gyu) was released.

A staff member of the drama said, "To film this scene, more than 300 people were added as support staff and all sorts of equipment was brought in to make rain and lightning and light efforts. To bring out a more active scene, more than 18 years of filming went on."

In the picture, Kim Hyun Joong puts himself in the mud and is fuming as you can tell the difficulties of the filming. The staff said, "Even when the camera wasn't on, Kim Hyun Joong was working things out with the other actors and doing ab exercises to not lose tension."

Meanwhile, "Generation of Youth" is set in the 1930s as it features the love and friendship of gangs in Korea, China, and Japan, and loyalty. It is broadcast at Wednesday and Thursday at 10PM.
