"You Who Came From The Stars" actor Kim Soo Hyun is playing ten roles in his role as an alien Do Min Joon in the drama.

The TV drama "You Who Came From The Stars," which aired its first episode on Wednesday, December 18, 2013, showed Do Min Joon who made his first appearance as an alien who arrived in Korea in the Cho Sun dynasty times from a UFO. Kim Soo Hyun then showed how the character Do Min Joon has been working as a businessman in Cho Sun dynasty, soldier, doctor, and college instructor, playing at least ten different roles in just this one first episode.

In addition, the part where Do Min Joon, played by Kim Soo Hyun, and Chun Song Yi, played by Jun Ji Hyun, who met twelve years ago, walk across from each other not recognizing each other has attracted the attention of the audiences.

"You Came From The Stars" is based on the records from the Choseon Dynasty on an unidentified flying object in 1609. The drama tells a romantic story of Korean star Chun Song Yi and an alien Do Min Joon who was dropped off to the earth 400 years ago. Chun Song Yi, the character Jun Ji Hyun plays in "You Who Came From The Stars," is a top star yet completely and perfectly alone. Jun Ji Hyun said on her character, "Chun Song Yi is the most comical role out of the whole drama. Chun Song Yi makes a lot of word related mistakes, and is not very bright." Jun Ji Hyun added, "I felt as if the character Chun Song Yi was like me.
