In June 2019, Bobby Au Yeung (歐陽震華) expressed he would be filming cop drama with Joey Meng (萬綺雯) again. Due to the conflicts between the police force and citizens, the new drama (衝鋒隊2019) directed by Jacky (李志倫) was suspended and Bobby and Joey tried out the role images for the new series (伙記辦大事), without arranging any interviews on 20th September 2019. The cast team members included Joe Ma (馬德鐘), Jeannie Chan (陳瀅), Matt Yeung (楊明), Cheung Kwok Keung (張國強) and Celine Ma (馬蹄露) and the public is aware of it after several artistes uploaded the photos online.
When Ming Pao (明報) contacted the film producer, Andy Chan (陳耀全), he explained it was unnecessary to handle in low-key manner and the filming would start in this October: “We are trying to apply for the procedure and it is difficult to comprise the artistes’ schedules. Jeannie plays a bad woman but she cannot cut her hair short due to shooting another drama. The role image is not fixed yet and we will allow the media to interview once the arrangement is confirmed.” He added the promotion activities for another drama, Airport Strikers (機場特警) had yet to arrange and the role images would be revealed, after the worshipping ceremony.
As Joe acted as a lawyer in the series (伙記辦大事), Andy accompanied him to the hearing at the court for preparation. Asking if he felt pressurised to shoot the drama during a sensitive period, Andy said: “I do not feel stressed as the shooting for Line Walker 3 (使徒行者3) series is ongoing and the location shooting usually begins first. However, it is different for this drama because of the manpower and we will be filming in the studio room in early October, followed by the location shooting in mid or end October.”
