Kim Jaejoong filmed for 40 hours straight under the heat.

Kim Jaejoong, currently receiving much love for his role as Kim Kyung Tak in MBC drama "Time Slip Dr.Jin," finished filming after 40 hours straight.

Kim Jaejoong's agency CJ Entertainment said, "He had deep acting scene with his father in the drama Kim Byung Hee with 2 episodes until the end of the drama for 2 straight days."

They continued, "There was a war scene in episodes 21 and 22 so there was a lot of outdoor filming. All the actors and staff members thus had to endure the heat wave to film. Kim Jaejoong is giving his all as well."

A staff at the filming set stated, "It was a very important scene for Kim Kyung Tak, so Kim Jaejoong stayed focused and gave his best while filming. Even after filming was over, he was so emotionally stirred that he could not stop crying. I was even worried that he was going to pass out."

Kim Jaejoong stated, "It was really said. Even after the scene was over, tears did not stop coming out so I realized that I was really deeply into the character of Kim Kyung Tak. The actors and staff members are trying their best so please keep watching until the end."
