Steven Zaillian

Over the past decade... while many businesses have pursued what I call 'business as usual,' I have been part of a different, smaller business movement, one that tried to put idealism back on the agenda.

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.

After decades spent in rewrite rooms surrounded by other shouting writers, I discovered that I work best alone. I like being in charge of my time, working out the problems according to my own rhythms and being able to nap. That's a big one, the napping on demand!
