At the press conference for the movie 'Asura: The City of Madness' on September 1, Jung Woo Sung called out his costar for sleeping so much on set. He said, "Joo Ji Hoon doesn't look at the script, and he sleeps on set. When there's a scene with Ji Hoon in it, that's the only time he doesn't sleep. He sleeps the most I've ever seen. I wondered if a human needed that much sleep."
Joo Ji Hoon then defended himself, saying, "I'm not sure if it's because I'm the maknae, but the director and hyungs let me do whatever I wanted on set. They told me to do my best and to be comfortable because I might be uncomfortable."
'Asura: The City of Madness' opens in theaters on September 28 KST.
