Alexa: (on "The Chronicles of Riddick") I always was interested, and always was fascinated by the idea of doing a science fiction film because there's no boundaries – it's free will of the imagination, and that I've always loved.
Alexa: The process is so different working in film versus television and the length of time that you have and the time that you have to explore everything because it's so different.
Alexa: Latex is very uncomfortable to wear. It's very hot, it's very uncomfortable. Yes, it's like wearing a balloon just that you can't breathe.
Alexa: I would never close any doors to anything and if it were a character that I loved regardless, I would definitely give it thought but that is my first love, film.
Alexa: (about her action figure) It's so bizarre. I like it. It's a funny thing to look at this little miniature toy, this tangible replica of yourself is funny but it's a huge compliment really, I'm flattered by it.
Alexa: I love to travel and I travel as often as I can. I don't stay in one place too long.
Alexa: (in a June 2004 interview) I'm reading Mutant Message Down Under which is a story of a woman, this aboriginal tribe in Australia, and I read a bunch of different things at once actually.
Alexa: Being raised in France primarily as a child I spent a lot of time in the south of France and all through Italy and we traveled so much. I think that's why I'm so used to being all over the place.
Alexa: I just hope to just carry on one step at a time and allow it to take its course really.
Alexa: (on her training for the film "The Chronicles of Riddick") The training was a life-changing experience. Before that, the gym was a foreign planet to me, so I didn't understand it. But I fell in love with the fight choreography and the weapon training and the wire work. The wire work was my favorite. I would do that any day of the week.
Alexa: I think it's a conscious choice of how you you're your life and what you allow to affect you and what you don't.
Alexa: (on being a physical type of person prior to making "The Chronicles of Riddick") I danced for a bit as a child, I did ballet and I was a bit of a swimmer but I was never an athlete until this and now I love it.
