Kwai Lun-Mei recently came to Hong Kong to promote THE STOOL PIGEON (SIN YUN) on Cable Entertainment News channel. This time Siu Mei in the new film played for the first time a tough girlfriend of a mob boss and had many action scenes. Siu Mei recalled that everyday after work she would find a lot of new bruises on her legs at the hotel, but she thought it was a lot of fun. She stated that this character was more direct emotionally, certain about love and hate. It was not too much like her. After the shoot she missed this character very much. Even Tse Ting Fung after watching her performance joked that she was "pretending to be nice" normally. Siu Mei also hoped that in the future she would like to work with co-stars who are full of masculinity like Lau Ching Wan and Simon Yam Tat Wa. Did she prefer to work with more mature actors? Siu Mei said, "I am in trouble now, I also like to work with Ting Fung again."
Having sun the film's theme song, Siu Mei pointed out that she was not singer material. Normally she went to karaoke boxes less than five times. She felt that singing in front of others to express emotions was very hard, thus when she went to the studio she was more stressed than making movies. The host asked to choose between keep making movies in two years, releasing a record or getting married, Siu Mei without consideration chose marriage. She expressed that since childhood she has dreamed about having a happy home, finding someone who would never leave her to get married and have children with; yet she has no plan to marry

The director also praised Miao Pu's performance as outstanding.
Miao Pu after THE BEAST STALKER reunited with Cheung Ka Fai. She felt very honored to be able to work with the six time Best Actor. She also pointed out that Ka Fai was serious at work, and would rehearse with her even for a very short scene. he was a great actor. Lam Chiu Yin also pointed out that another actress Kwai Lun-Mei's performance had no reservation. In the film she drank with Tse Ting Fung, at the time she truly drank and had more than one bottle at that. Tse Ting Fung did not drink. When he saw Kwai Lun-Mei drank, he followed suit. Finally he was all read from half a bottle, which he felt was rather fun.
At night Lam Chiu Yin attended the premiere and took time to enjoy Chongqing's hot pot casserole. He stated that it was very hot but a lot of fun. At the premiere, a male viewer screamed "I love you" to Miao Pu, another male fan even rushed the stage with a rose in hand. Chongqing viewers liked the ending because it was different from the usual police film. Lam Chiu Yin also said that if he would make a sister chapter to THE STOOL PIGEON, he would like every actor to keep going with him.
