Daniela: (on her first work while in Portugal and still in high school) It was a teeny tiny paycheck and working almost six days a week and hours on end, and there was kind of no support as a kid in high school. We had no tutors on set with us or anything like that, so I was literally fighting for my grades and fighting for a job that I loved.
Daniela: (on her role as Special Agent Kensi Blye in NCIS: Los Angeles) She had everything to do with me in terms of speaking languages and being well-traveled.
Daniela: (on her experience, when she was 19, meeting Jewish youth for the first time) I've never been around as many Jews in my entire life. Here, you don't feel the need to explain to people who you are. I am meeting people who eat kosher for the first time ever.
Daniela: (on the effect having one black eye, due to a birthmark, might have in her acting and her career) It starts the conversation, if anything. But I don't think it's ever gotten me a job or lost me a job. When we're shooting, sometimes they need to light my eye in a slightly different way. Otherwise, it looks like there's a big shadow over it. But that's pretty much it.
Daniela: (on her black right eye, due to a birthmark) This is my eye, my little trademark.
Daniela: (on her right eye's birthmark that makes that eye black) No, I can't stay serious. That's not true at all. It's a birthmark called nevus of Ota. It covers the whole white of my eye and darkens it. The square of the eye, the white part, is completely dark on my right eye, not just the iris. It's very common in Asian people but quite rare in Caucasians. It doesn't affect my vision or anything like that.
Daniela: (on her tendency of talking with a lot of hand moves, like the Italians do) Portuguese do that. We're very aggressive speakers. I remember when I was with one of my roommates in New York — and she's Portuguese, too — and we were in an Apple store talking about a computer in Portuguese. Some guy comes up to us and goes, 'Hey, hey! Peace, peace! Stop arguing.' It's not arguing. This is really just how we talk.
Daniela: (referring to Portugal) I still love the country.
Daniela: (about her son, River, before he was born) It's amazing how in love I am with this little person I've only seen on a black and white screen. I'm starting my own family and there is no other feeling like it.
Daniela: (on having a son with David Paul Olsen) I'm so thrilled about this new chapter as a parent with David.
Daniela: (on being a Portuguese Jew) There's I'd say between four- and five-hundred [Portuguese Jews]. Not a lot out of 10½ million to 11 million people. My family is probably the biggest family there. But coming from a small community makes you want to follow the traditions of your family much more.
Daniela: (about her happiness regarding her first born son River) We are so happy, so thankful and feel so blessed to have brought him into the world.
