Alan Arkin

What I look for these days is that I don't have long speeches, the characters gets to sit down a lot, I don't have to learn any foreign languages, and it doesn't shoot in Minneapolis in February. That's mainly what I look for.

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.
