I feel lucky that I got to work with some of the big legends in town.
I was pretty nervous when I met Robert De Niro. I kind of felt like a kid in a candy store for the first time. I couldn't wipe the grin off of my face. But Bobby DeNiro was really, really sweet and made me feel very comfortable. He's very low-key and just a superstar professional, and totally someone to be admired.
I've always been a very outdoors sort of girl. I'm more a tomboy than a girly girl.
I remember being at Greenblatt's on Sunset, and some guy just walked straight up to me, and he had some bling on and whatever, and said something about a party down in Malibu and asked if I would jump in his car and go to the party. All I could think was, "Who are you? I don't know you, and I don't care about how good your car is."
[on her character in Chuck (2007)] Sarah is very strong. She's really intelligent and she's very physically capable. I like to put that into my own life as well.
