"I only sleep an hour a day."

The star of the SBS Wednesday Thursday drama "You Who Came From The Stars" Kim Soo Hyun is sleeping only an hour a day, according to a staff person from Kim Soo Hyun's agency, Keyeast. From Monday through Sunday, Kim Soo Hyun sleeps only in the filming scenes. The same staff member from Kim Soo Hyun's agency, Keyeast, said, "Kim Soo Hyun also has a commercial filming schedule that was booked before the drama. He films the commercial, then runs to the drama filming scene. He is rarely out of the drama filming scenes."

Since Kim Soo Hyun plays an alien who has been on the earth for four hundred years, he also needs to film parts of his scenes in a special film set to portray the atmosphere of the Cho Sun dynasty.
