Think ofAndy Lau, 59, on the big screen and your mind would most likely conjure images of the Heavenly Kingas a hero who a) saves the day and gets the girl and b) saves the girl and gets his way. Throughout his almost four decade-long career, he has mostly played good guys, which shouldn't be a stretch for him since Andy, in real life, is known for being an all-round good guy too.Andy once revealed in an interview that he rejects playing stereotypical villains, and avoids risqué sex scenes in his movies for one reason: He doesn’t want to “teach his fans bad things”, especially the young and impressionable ones.But if a role really, really needs him to be on the dark side, or if the character does something criminal, Andy has one requirement before he signs on to play it: that the character must die by the time the end credits roll.
