As Kudo plays a husband who was violent to his ex-wife, he said with a wryly smile that this is a movie he can't show his daughter and he can't identify with his character at all. However, there are indeed such people in this world so he had to show this side of his character through his acting. Tanaka also chipped in to say that it had been a very stimulating and exciting experience during the filming but the scene when she got beaten up by Kudo would have to be on top of the list. It left an even deeper impression on her because that was filmed on her birthday last year and she had just received a cake from the staff moments before she was to be "strangled" by Kudo.
Asano revealed that the reason why he decided to participate in this movie was the script. As most of his characters to date tend to have such unique traits, he had always wanted to act as someone who doesn't cause anything in the story and just goes with the flow of developments. As such, he could finally tap on his experience and pour everything into this character.
Minami who is making her acting debut in this movie, said that she was very unsure about what to do but received advice from the director to react accordingly to her co-stars' acting so this helped her to overcome her fear. Tanaka also praised Minami who plays her daughter for being very direct in her acting and gave her a lot of inspiration as a result. Kamata and Arai also had good words for Asano who plays their father and said that they had a lot of fun during the filming thanks to him being like a true father to them.
