After 'Urinetown,' 'Avenue Q' and now 'Mormon,' is there an envelope remaining to be pushed?

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.

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.

For the three years I lived in New York leading up to moving out to Los Angeles for 'Mad Men,' I was an office temp at Ernst & Young in Times Square. That's about as desk-jobby as it can get. There was a lot of, 'Go two floors up and make a copy of this and then bring it to me.'

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.

The amount of times my wife has rolled her eyes at board games is impossible to count.

I don't have the confidence to pull off a moustache.
