To my mind there are not enough things that show the Nazis as human, as smart people, charismatic people, who are not inhuman naturally. But who are able to be fantastically inhuman when they choose to be.

Frankly, as much as I love to improvise, it hasn't been difficult to stick to the script on 'Mad Men.' The writing is so precise, and the story so carefully crafted, that I don't think there's room - or need - for ad libbing. I could never come up with dialogue as lovely as these writers do, anyway.
