The film also marks the ninth collaboration between actors Lau Ching-Wan and Louis Koo. When the directors first approached him with the screenplay, Koo thought that they were playing a trick on him, since his character was much older than Lau's character. To prepare for the role, he had to apply makeup, gain 30 pounds and get a new hairstyle.
