I agree, Ang... Gwynne's technique of delivery is unique and not heard often, especially today. I studied voice-over for a while, and my favorite teacher, Will LeBow, most popular for a character on the cable show Dr. Katz, taught us the same technique. He called it "believable stumbling" or something to that effect, and it is normal to speak this way... so much so, that the listener often identifies more with the character without being aware.

Another thing he taught us was to use our arms and hands when we speak. The vocal delivery can be climaxed, balanced, and completely controlled by using one's body to push the presence of the voice.

Point is, I can just imagine the studio full of RMT players all waving their arms and hands about while performing some of these roles. They must have had an absolute BLAST!
