My improv definitely shows a different side of myself, which is more true to what my real humor is and what my real personality is, and I think - I guess 'wild' is a good word for it. I'm still sweet! But I won't let anyone walk all over me.

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.
