Actor Christopher Walken is tops in employing a deadpan, inscrutable facial expression that's difficult for other characters to read. This makes him either a generic everyman, or else an eerie stranger, depending on what the role calls for. And that set up makes it all the more devastating when he loses it.
Every role he seems to have that quiet calm until the right moment when he needs to snap, and then you tend to sit back out of habit since it’s so in your face awesome that you kind of have to take a quick second to readjust and get used to it. And then, like I said, he goes back to being quiet.
That’s what makes him so awesome.
Filmmakers know Walken's strengths and use it to ultimate effect in movie after movie. Watch Walken go completely bonkers in video clips from five movies you know and love at TVOM.
