Sure, Jon Benjamin looks nothing like Archer, so it stands to reason that someone else was the model for the character, but, as it happens, none of the voice actors were models for their own characters (I had thought that Jessica Walters and Aisha Tyler might have been).

So...who are these people? Here they are. I was kind of amused to find that Lucky Yates—the voice of Krieger and who I know from Good Eats—was the model for Ray.
