Fans might not realize it, but Charlie Townsend did show his face one time — and only once — during the original five-season run of "Charlie's Angels."

Cool bit of trivia but its not the actor who played Charlie over the years. I wonder why he was not available. Supposedly the actor who played Charlie would do his audio work and was never really around the set. We never see Charlie lips move when he talked so the actor they used for the visual back of Charlie may not have been the voice. So this could explain why anyone could have played Charlie in this scene.
