During the press conference for 'Hyung' on October 26, D.O talked about his co-star Jo Jung Suk, who plays his older brother.  

D.O first complimented Jo Jung Suk with, "He's always serious and relaxed, but when he acts, he's humorous and flexible.  I want to resemble him."  However, in the movie, Jo Jung Suk's character could be detestable and abusive, so D.O was asked, "Seeing as how you get immersed in your character, wasn't Jo Jung Suk unlikeable to you in real life?"

D.O replied, "There were many times when I really did hate him," making everyone laugh.  He continued, "He was really detestable.  I hated him a lot of times," but then said, "I was always impressed by Jo Jung Suk's image like this, though.  How could his acting be like this?  I was only surprised watching him."

The movie comes out on November 30!
