Steven Ma (馬浚偉), Josephine Koo (顧美華) and Jennifer Yu (余香凝) attended the pre-shooting ceremony of the movie version (生前約死後) on 22nd May 2019. As the film director and actor, Steven expressed the details about the bonding between the mother and son was very detailed when compared to the stage play. He suspected he suffered from a skin allergy because of his mood swing after shooting a crying scene a few days ago: “I feel I become silly due to my identity and losing weight for my role character. Sometimes, I am too anxious and throw my temper at the operating director and vice director. Poor them.”
