Andy Lau Tak Wah is an icon in Hong Kong. He's appeared in more than one hundred films, and several TV series. He's one of the "Four Heavenly Kings" of Cantopop. He's the pitch man for a variety of consumer goods. He has appeared in several public service advertisements. Everywhere you go in Hong Kong, you'll see his face: in DVD shops, music stores, on billboards and on television. And it's a very recognisable face: aquiline nose, high cheekbones, a jawline so sharp you could shave with it.
