I received so many hate letters when I breast-fed a starving baby in Africa. I was in Sierra Leone in 2009 and I was weaning my child at that time - she was not there with me. There was a hungry baby who was crying because his mother had no milk, and I thought, 'Why throw away my milk if I can give it to a baby who needs it?'

I have tried my whole life to represent my Mexican roots with honor and pride.

There's a lot about the character. It doesn't always happen, but there are some characters you really create a relationship with, almost as if they were your friend. And you never get into their heads again or think like them.

I have never denied my background or my culture. I have taught my child to embrace her Mexican heritage, to love my first language, Spanish, to learn about Mexican history, music, folk art, food, and even the Mexican candy I grew up with.

I also have a film coming up called Breaking Up, and my part in that was not written for a Latina, and my character is not particularly pretty or sexy or exotic.

I'm good at working, but I'm very good at playing.

Art and activism seem to go together naturally, the idea being that if you're an entertainer, you can have a voice, and if you have a voice, you can make a difference. But if I were not an actress, I would still try to extend myself beyond my little micro-universe of my job, family and personal joy.
