Alexandra: (on getting in shape for the action scenes in the movie San Andreas) My first concern was the role and the lines. For the movie I'm doing now, it's the same as the Percy Jackson movies; I'm physically active and really focusing on getting more muscle and getting in better shape because of the action required.
Alexandra: (on getting in shape for the nude scenes in True Detective) It was very strange because I actually did not pay that much attention to losing weight or getting in shape before that scene. I think because I was so nervous instead of just flat-out eating... I try to stay active and that kind of thing, but I didn't fixate a lot on the weight.
Alexandra: (on her attending the 2014 Elton John AIDS Foundation Academy Awards Viewing Party) Celebrating this wonderful business we get to be a part of and supporting a great cause.
Alexandra: (on her appreciation of Charlize Theron Charlize Theron is perfect. She holds herself with so much poise and grace. I don't know if she looks so good because she has the best body or because she has the confidence to feel comfortable in what she's wearing.
Alexandra: (on find the right stylist for red carpet events) Finding a stylist is a little like finding a date, you have to find who is right for you.
Alexandra: (on dressing for the Red Carpet) I think because it's so different from my norm it's all the more fun to get dressed up and be a princess for a night
Alexandra: (on her laid-back casual style) When I have no appointments, I spend the day in pajamas and go to the dog park in pajamas. I'm very casual.
Alexandra: (on the music she likes) I love all different kinds of music. Besides Imagine Dragons, I'm really into the Lumineers, Ryan Adams, Counting Crows, Elton John and a lot of country music right now. Kenny Chesney and Taylor Swift's new albums are always on.
Alexandra: (on her experience filming a music video for Imagine Dragons) I'm a fan of their music, so when I got the call that Imagine Dragons was interested in me for their newest video, I was really excited! We shot in New York the day Hurricane Sandy started to hit. Our shoot got cut short, half-way through the day, because of the storm. It became a pretty memorable shoot with everyone trying to work out if we were going to be able to get enough footage before the storm hit! Luckily we did, and I think the video turned out really amazing. It was fun to be part of, and a different experience than anything I'd done before.
Alexandra: (on her role from New York city to LA) The transition to LA was exciting, but also difficult because it's a very different city than New York. The biggest problem for me initially was driving... I failed my road test three times and was taking the bus around LA, which isn't as easy to do as it is in New York! But I've made some amazing friends here, and finally got a license and a car, so I feel more at home now.
Alexandra: I'm very into fantasy films.
Alexandra: I'm really easily affected by horror films. I have pretty strong reactions to them.
Alexandra: To be an actress and act crazy is really fun for me, to be able to be acting like you'd never be able to act in your real life and scream and freak out. It's an interesting test for an actor.
Alexandra: I love stories about people that, whatever situation they're in, you can relate to them in a way.
Alexandra: I never know what's going to happen or what opportunities are going to be given to me. I've found with the opportunities that I've been given have made it possible for me to explore different characters and exciting stories.
