Bill Hader

When you saw Jon Lovitz or Dana Carvey or Phil Hartman doing something, they were acting. It was real acting. Like, they were acting like that person. They weren't like - it wasn't even like they were really trying to go for a laugh, especially in Phil Hartman's case.

My wife and I were on our honeymoon in Turks and Caicos, in the middle of nowhere, and I'm sitting on this deserted beach, and I see one lone person walking along the shore. He walks right up to me and says, 'I love 'Laser Cats,' and then just walks away.

It doesn't occur to me that I don't drive a cool car until I hang out with Jon Hamm, who picks me up in what looks like a Transformer, and I think, 'Oh, that's what movie stars are driving. I guess I'm not a movie star.'

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.
