Dance has helped me with everything. It was a great foundation for discipline, hard work and, unfortunately, the ever-elusive idea of perfection. It lends itself easily to fight choreography, because that's what it really is. Choreography. And knowing how to move with someone.

I love Cheryl [Hines] so much and had so much fun with her. Off set we got on so well and would tell stories.

[Adrienne Shelly] explain exactly what she was looking for. This was her movie [Waitress].She also wrote the songs that I sing in it. She wrote everything. She chose the colour of our outfits; she designed the set of the diner. She was very, very involved at every level.

Cheryl [Hines] and I sat through two screenings at the Sundance Film Festival and during the second one, we said to each other: "You know, we don't have to get sad about this. Let's try to enjoy this. Let's just watch it. It's a happy movie [Waitress]."

The thing I loved about this movie [Waitress] when I read the script was that it was exactly the kind of film that I love to watch. It's not just funny, it's serious, just when you need it to be and true to life in a way.

Sex has never been something I've done in my career - at all.

Freddie [Highmore] is great in the movie [August Rush]. It comes out this Fall and I play a young cellist, a prodigy, who is touring and doing concerts. She's very young and has a one-night fling with an Irish rocker, played Jonathan Rhys Meyers, who is also a really talented musician.
