Arthur Hiller

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.

I watched Ali, studied Ali, and I studied Sugar Ray Robinson. I watched them display showmanship. I watched them use pizzazz, personality, and charisma. I took things from them and borrowed things from them because boxing is entertainment.
