Simon Yam is easily the most versatile actor in HK. He can be incredibly smooth and charismatic as in A Bullet in the Head or vicious beyond belief as in Dr Lamb. But like Michael Caine, Yam can be justly accused of taking just about any work for a paycheck. He has acted in nearly one hundred films. So he has shown up in a lot of really bad films - sometimes only for a few minutes - but even in these he classes up the screen with the style he always brings with him.
