On 13th December 2019, Aaron Kwok (郭富城) discussed about his acting experiences at a seminar and expressed about playing many emotional roles in recent years. When asked if he acted a happy role previously, Aaron said: “I wish to but people seldom approach me to film comedy movie. (Perceived as a stern man?) No idea. Hopefully I will shoot a comedy film in the future. It is very challenging to play a complicated role and I almost fail to differentiate the reality when filming Murderer (殺人犯) movie. I even dream of killing people in the film and ask myself if I really kill somebody upon waking up. I start to feel relieved once knowing it is a dream. (Look for psychologist?) No need to. I have my own method such as training and going for car racing to distract myself. Since I have two daughters now, it makes me forget about it easily.”
