Well, I’ll be damned: Christopher Walken was a former child actor! Man, not only is it difficult to picture Christopher Walken as a child actor, it’s difficult to picture Christopher Walken as a CHILD, period! However, at the age of 10, while he was still going under his birth name, “Ronnie Walken”, he made a brief appearance alongside Dean Martin and Jerry Lewis in a sketch on their television show, The Colgate Comedy Hour. You can see little Ronnie Walken at the 11:38 mark as he gets into an arm wrestling match with a machine and the kid clearly has trouble keeping a straight face throughout Martin and Lewis’ antics.
