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.

Im pretty quick to delete something off of my phone if its become obsolete. And things like RSS readers have made life easier - all of the headlines are going to be related to a topic Im interested in.

The 12 years that I was improvising are why I got the number of commercials I got when I was in New York and why I got The Devil Wears Prada, and its why I even got in the door for Mad Men.

Before 'Mad Men,' I definitely had very dry spells and I know what those feel like, and I don't think that ever leaves you as an actor.

I'm a Joseph Abboud fan. I'm a Hugo Boss fan. I'm a Brooks Brothers fan. As far as suits go, those are my go-tos.

My only foray into anything stock-market-related was in my eighth grade social studies class. I have steered clear ever since.

I would like to ban people being allowed to text while in a crosswalk.
