Francis Ng Chun Yu earlier worked on the suspense action crime film PAY BACK (LIP SAU JH). In the film he played a kind father whose wife died from depression after their daughter was raped and murdered. His mood drastically changed as his heart for revenge put him on a road of no return. Chun Yu said that this character was very challenging, but as a father would he worry that his son would feel his father was a bad guy after watching this film? Chun Yu pointed out that his son was only a child and all he had to do was buy him a toy. He would not reject certain role just to pretend to be a good parent, because reality and action could not be mixed together. Reportedly, Chun Yu in order to get into the character almost "hid himself" on the set. He did not even say much to his assistant. Chun Yu joked, "Mainly it was too hot, I was just too lazy to talk. On the set I had a lot of fun from chatting with many girls."
