Actor Hyun Woo fainted in the jungle.

On May 10, the press conference SBS 'Law of the Jungle in Lost Jungle & Ireland' took place at the SBS building in Seoul. 

Hyun Woo shared he passed out during filming. He explained, "It was so hot to the point where we couldn't do anything during the day. The captain said we should get things done at night and get good sleep during the day. So I only got one hour of sleep on the first day."

He continued, "I had to sleep when the sun came up but I couldn't because it was so hot. I was so hungry and everything was so difficult but I started doing things. I thought I was doing fine but I felt so dizzy, and then I heard the members' speech starting to slur. I thought it was a movie for a moment. I sat down for a second but when I opened my eyes, I was laid down in the corner with a needle in my arm. I don't remember what happened throughout that time. It was that much of a severe condition."

Producer Cho Yong Jae added, "At the time, we put the thermometer on the ground and it exploded because it was over 50C (122F). All the members equally had a hard time."

The first episode of 'Law of the Jungle in Lost Jungle & Ireland' is airing on May 11.
