Mohamed ElBaradei

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.
