I guess the most difficult thing for me was living up to my mom's expectations. I was always scared that if I didn't do things in this certain way, then my mom just wouldn't think I was great. That's something that was difficult for me growing up.

I love martial-arts movies. I grew up with my dad watching kung-fu theater every Sunday. So it was kind of my thing.

I'm not really easy to live with! There needs to be unlimited patience and unconditional love. Men I've known before loved my independent spirit and were proud of my success, to the point that they'd become jealous of the time I devote to my career.

When I think about myself at 15, I can't relate to myself at all. I thought I knew everything.

When you're doing martial arts, you feel like you can master certain skills and be so much more in control of who you are, so that really appealed to me.

What's interesting about the movie and characters is that they're one thing to the world and another thing in their heads.

It was hard not to feel violated [in Stone movie], 'cause I have to go home after walking in these shoes all day. It plays a number on your head. Some days I came home and was really upset; it was hard to see the baby [Jovovich's 2-year-old daughter].
