The brilliant costume designer Mary Zorphres had done all this research on West Texas in 1980. Every woman looked like that. At a certain age, they would get their hair cut off, let the gray go in, get that permanent, and wear those big glasses. She gave me a beanie bra so my boobs would hang down, and these old dresses. My hat's off to her, because I thought it was perfect for the movie. It was so great to have some comic relief right at that moment. No Country For Old Men is such an intense film.

I knew Steve Carell because of Little Miss Sunshine, so I felt very comfortable with him. Maybe he always does it to guest stars, but I felt as though he was being particularly funny with me, and particularly stretching the boundaries of improvisation. He's such a comic genius. I hate to use that word, because everyone throws it around, but Steve Carell is channeling something.

There's always that key to every character that lets you go to those places you need to go to. No matter how much you might hate the character, it makes you understand it.

I never have broken up in comedy, ever. There's something about me that I just don't break on camera - maybe because I'm just so cheap, and I know how expensive it is to shoot - but I broke on Sordid Lives, and I broke on The Office. Those are the only two times in my life.

I never have compared myself to Jessica Tandy in any way, and that's such a great role model for me to look at. I'm seriously going to put pictures of her in my dressing room and commune with her from now on, I think.

I was up at Big Sur with Christopher Reeve and Christine Lahti, doing this woman in a big fat-suit - Mrs. Bassett in Tennessee Williams' Summer And Smoke - and my husband was in the show too, playing Lahti's fiancée. Every night he'd be proposing to beautiful Christine Lahti, and I'd barrel onstage in this fat-suit. I hated it! But I did it, because by then I knew that that was my casting.

I built a career on my archetype, and I'm grateful, but I'm trying to stretch.
