Inside joke: While watching seasoned actor Fai (played by Lau Ching-wan) appears in a film award ceremony as a nominee of Best Supporting Actor, a friend of him quips, "He should be the next one in the queue who wins an award." In real life, Lau Ching-wan has been widely hailed as a character actor and yet he failed to win any film award prior to this film albeit being nominated for Hong Kong Film Awards for six times. He has finally won one for his performance in this film.
