- Willa: For an actor, I am actually a really bad movie watcher. I should have seen every film out there, but oddly I have not.
- Willa: (on her style) I go with the mantra 'what feels good, looks good'. I like long floaty clothes that don't restrict me, and I live in flat boots. I love Sienna Miller's look, especially when she went all 1960s after filming Factory Girl.
- Willa: When I was little, one and two, I used to sit in front of the TV and my mom told me I would point to the TV and be like, 'That's what I want to do.'
- Willa: (on having Brian De Palma for a step-dad) It's great because I know I have somebody that knows what he's talking about supporting me. He never pushed me into this, and he never pushed me out of it. He just always let me do what I wanted to do. He's let me know that no matter what decision I make, he'd always support me through all of this. He's always given me advice about how to stay true and how to not get corrupted by all this stuff that happens in Hollywood.
- Willa: (on dealing with the paparazzi; in a 2008 interview) Thank the Lord I don't. I'm dreading the day. I've been with friends who've had to deal with it and it's most annoying thing on the planet. I'm not at the tabloid point of my career.
- Willa: I've met girls who have done the craziest things in their life and they are my age. Girls getting pregnant at 16 and 17! It's the most insane thing in the world. I'm mortified of getting jaded by it all. I always need to get myself out of L.A. for a month or two and relax somewhere else.
- Willa: (on taking advice from other people) My goal is to keep my head on shoulders and my feet on the ground. Any constructive criticism I always take advantage of.
- Willa: (on being drawn to more complex characters) I'm drawn to more realistic things in life, to real people. I like putting myself in the shoes of others. It's very hard for me [to imagine being] in unrealistic shoes like a superhero because that's not something that actually exists.
- Willa: (on her role as Kaitlin on "The O.C.") It's so much fun to play the bad girl, everybody has that little side of them they never really get to get out.
- Willa: (about working with co-star Mischa Barton on "The O.C.") Whenever Mischa walks into a room, she just looks phenomenal. You can't help but get a little inspiration from her.
- Willa: I couldn't stand high school! I knew the first day I got there I wanted to leave. It just wasn't for me. It wasn't the place I was suppose to be.
- Willa: I'm the clumsiest person on the planet. I trip all over the place. I'm not too hand-eye coordinated.
- Willa: (on her favourite TV show) South Park. I've been watching it for so long, I can't not watch it - I'm addicted! I can't get over the four kids; they're the funniest things on the planet. Every episode makes fun of something that shouldn't be made fun of - and that's a complete joke.
