Do you find his acting one dimensional?

Ironically Walken himself kind of disagrees, I read that he thinks the role he played in A Business Affair was more like himself than any other role he plays, and as for his speech patterns - it's normal for him to talk like that - it's what makes him Walken. Of course I can't say anything bad about him because well i'm afraid he'll come after me if I do.

He has unique mannerisms and speech that is his trademark. So yes he may be limited of range but what he does have is highly unique and distinct. I love seeing him in films and wish he was getting better roles. It is sad to see the once great actor getting relegated to the direct to dvd bin. Both him and Ray Liotta have been in one d- grade low budget poofest after another lately.

Watch him in "Around the Bend", "Blast from the Past", "Who Am I This Time?", and "The Prophecy". He's one of the most versatile actors I've ever seen.

Christopher Walken has a dimension of his very own.

He's an idiosyncratic guy and he certainly has his own style but I wouldn't say he always plays the same character, I think he's always being given the same character. I've no doubt many of the parts he's done in the past couple of decades were written for him in advance.

But I also think he takes on too many lousy parts and then ends up drilling through the bland script on autopilot.
I guess, like so many chronically type-cast actors, he shines the most when he's cast in an atypical part.
