Director Kim Yong-hwa has nothing but praise for his main cast for The Moon.

Expressing satisfaction with the exceptional synergy among his lead actors – Sul Kyung Gu, Doh Kyung-soo and Kim Hee-ae – the director said, “They are all such skilled actors that even if they were acting separately, their emotions, tone, and manner were perfectly synchronized, which surprised me.” 

EXO’s Doh Kyung-soo plays an astronaut (Sun-woo) stranded in space in The Moon.

In the thrilling and emotional space movie, Korea’s first manned mission to the moon ends in a tragic disaster when an explosion occurs on board. Seven years later, a second human spaceflight is launched successfully but a strong solar wind causes it to malfunction. One astronaut Sun-woo (Doh) is left stranded in space. Facing another fatal catastrophe, the Naro Space Center turns to its former managing director Dr. Kim (Sul) to help bring Sun-woo back home safely. In the film, each of the three main characters is in a setting that is different and away from the others.
