Talented actor Joo Won appeared on SBS radio program 'Cultwo Show' on October 19 to promote his upcoming movie, 'That Guy.'

He revealed that he gained 8 kg (~ 18 lbs) in order to film the movie, stating, "I first lost weight for the character, but I personally somewhat felt like I was getting further away from the character.  I thought that I actually would need to gain weight, so I exercised and also ate more.

"Of course everyone has his or her own opinion, but I'm the type who feels that I need to create the image before the first filming in order to have trust in it.  Whether it's the clothes, the hair, or the skin color, I need to create the state in order to become that role, so I had even gone tanning often.  He's a young man of the sea, so I felt that he had to be darkly tanned and plump."
