There is no doubt that Lee Min Ho has been through a lot in the filming of his DMZ documentary. During a recent press con, Lee Min Ho revealed that it was indeed one of the most challenging projects that he had undergone.

At one point, he even said to himself why he agreed to do it. He even says that he was expecting a lot of things to see in DMZ, however, he jokingly said that what he came across instead were land mines.

According to The Jakarta Post, one of the most challenging things that Lee Min Ho did during the documentary's filming was when he stayed up all night just to take photos of mountain goats. He did this at a very freezing temperature of negative 20 degrees Celsius.

He also said that he had also climbed up a very steep mountain and went down on it again, which was about a whole kilometer high. However, Lee Min Ho also revealed that it was very exciting for him to go around the place during the first days.

But as weeks went by, he realized that it was indeed a very exhausting and tiring place to shoot. The actor even considers DMZ as the worst place to film in Korea, implying that the experiences that they went through during the documentary's filming was not an easy task.

Reports also claim that Lee Min Ho examined a dead elk, as well as touched a snake. According to Soompi, Lee Min Ho concludes the press on saying that DMZ is proof that Korea is still at war with each other.

With his experiences in the filming of his documentary, Lee Min Ho sure knows how to prepare for his upcoming military enlistment. Lee Min Ho and the rest of the documentary's staff spent roughly two years in its filming.
