Mia: I'm very surprised at my career because I think I've been able to do exactly what I want to do. I've been doing theater in NY at Lincoln Center last year, I've done this TV show that I'm very proud of which is one of the best TV shows in the States and I'm able to do blockbuster movies, but then I'm able to do independent movies and just keep working in my first language which is Spanish and keep the doors open to go back and shoot in Argentina. So I'm just excited to keep it very eclectic and with a large variety, which I like and the fact that I'm able to work both in Spanish and in English gives me a much bigger array of characters to play and that's how you keep acting.
Mia: I don't know what I'm going to do. I have some offers for Argentina and some for here. I haven't decided if my next movie will be in Spanish or in English so I have to make up my mind and make a decision soon.
Mia (on doing the choreography for the movie Tango): Ashley [Judd] and Salma [Hayek] had to do this tango. And the choreographer had no idea how to dance tango. It was hilarious. This woman had choreographed this whole tango dance like it was out of one of the Zorro movies, you know, very ﬂamboyant, with ﬂamenco steps! So [director] Julie Taymor very nicely said, "Thanks a lot." And then I helped her with some tango steps and we kind of put this 1920s European Tango choreography together. But it was a collaborative effort... I'm from Argentina, so when someone comes with ﬂamenco steps, you know that has nothing to do with tango. Any Argentine could tell you that.
Mia: Hollywood is kind of a bad world.
Mia: I'm a total carnivore.
Mia: Naturally, I'm pretty physical.
Mia: The other day I had a running scene, and I had two hours until my next scene. Instead of going back to the trailer, I kept on running for an hour.
Mia: If something's important to you, you make time for it.
Mia: My parents were overprotective because you could get kidnapped and bombs were exploding in the streets.
