Today concludes our week long coverage on "Sin City," with Jessica Alba and Benicio Del Toro talking about the picture, below. Here's what they have to say:

Q: Your character was topless and bottomless in the comic book. Why play the character?

JESSICA: I wanted to do this movie because Robert Rodriguez was directing it, first and foremost. I didn’t really know it was a comic book when I read the sides, when I saw that he was directing something. I just tell my agent every month what is Robert doing? I want to do something with him. And Lee, one of my agents, has a really good relationship with Robert and said, “You got an opportunity.” And I was like, “Excellent.” So I took that opportunity and ran with it. I auditioned the old fashioned way, went in for the casting director, put myself on tape and he had to approve. And it was like a week of “Does he think I suck? I just don’t want him to think I suck. I don’t care if I get the role. I just don’t want Robert to think I suck.” And I he didn’t think I sucked and he came down and I read with him and I looked at the, by that time, I looked at the graphic novel and all the pictures. I then found out she was a stripper and was bottomless and topless and, nudity was an option. We could have done it if we wanted to, I just felt too—it absolutely was an option. Robert said that we could do it if we wanted to and obviously it would have been more authentic. I just felt like dancing around with a lasso and chaps was gonna be sexy enough, I think being nude, for me, would have been distracting and I really couldn’t be bottomless for my dad. He would really—I don’t know, he would disown me and freak out.

Q: How do you explain your character's, Nancy's, relationship with Bruce Willis' character? Is he almost a father figure to her?

JESSICA: Nancy doesn’t think of him as a father, she thinks of him as her knight in shining armor. So I just came at it from that point, so she just waited till she was old enough to be with him and have that relationship completely. I think she always looked to him as her soul mate from the beginning. She’s kind of an old soul from when she’s a little child, talking to him and reasoning with him, saying that she’s trying everything and she’s going to write him and so, I didn’t think it was creepy at all.

Q: You have three major films opening this year. Does this change things for you?

JESSICA: I’ve been doing this for 11 years so it defiantly isn’t an overnight thing and if people then know about me, I don’t entertain or act for myself or else I would just act in front of the mirror, so I actually like having an audience and people being effected by stuff that I’m in. I love entertaining and they all happen to come out this year and the more, the merrier.

Q: Benicio, how did you approach your character?

BENICIO : I was approached by Robert; I think we met at the Vanity Fair thing and she said something really strange, like, “Don’t cut your hair.” And my hair was pretty long, he goes, “Don’t cut your hair.” I go, OK. Then I met him here at the Four Seasons and he showed me—he had done a trailer of the opening sequence of the movie and it just looked amazing. I wasn’t familiar with the books; I was familiar with Frank’s work in Batman and stuff and since then, my preparation was really talking to the Wizard about—he got that nickname, I gave him that nickname. We just walked in and everything was green and I had seen how it looked already cause he had shown me the beginning of the movie, the opening sequence. It was like being in the office of the Wizard of Oz thing.

Q: How did it affect your process as an actor to take direction from both Robert Rodriguez and Frank Miller?

BENICIO : One at a time. That’s it basically. I mean, I think that .I’m attentive to like put a face with the director. I, for the most part, I turn to the wizard, cause he hired me. But I did have conversations with Frank, and Frank did have input on stuff; a lot of stuff.

JESSICA: It was very self-indulgent I think, because we just kind of got to talk each director’s ear off about our characters, and we kind of really like talking about characters we play and ourselves cause we’re all sort of narcissistic.

Q: What's it like for Latin American actors in Hollywood these days?

JESSICA: I don’t know Benicio’s experience, but it’s a lot different for me cause I only used to get breakdowns for Maria, the Janitor’s daughter messing around with the white kid and it was such a classist bizarre thing cause I grew up in the US. My mother’s white, my father’s Mexican and my father is very dark and my mother is very fair and I came out how did and they always want to pigeonhole you and it’s bizarre and we’re just people living in society. And I never think about it and people make me think about it. And this industry has definitely made me think about me being a Latin girl, up until I was 18 and did "Dark Angel" and Jim basically, “You are the future of the race.” And that basically what "Dark Angel" was that you are basically a mixture and you’re not going to talk about it. It’s done and you are just a human being going through the struggle of whatever you are going through on your journey. Now it’s very liberating working with people who aren’t going to pigeonhole you as the janitor’s daughter.

BENICIO: Not only in the acting, there’s a lot more filmmakers than probably when you started which is saying some class. There’s a lot of Latinos right now, a lot of filmmakers and writers that are Latin too.

Q: Does filming in front of the green screen allow you to be more creative?

BENICIO: For me, it was intimidating when you walk in and everything was green and it looked like puke. But after that it was like, it reminded me of theater—I trained as a theater actor and you had a bare stage and you had to pretend, one prop and you are in the middle of 8th Ave. and traffic is just going by. So it reminded me a little bit of that and that made it fun, going back to basics in some ways for me.

JESSICA: I’m not very experiences in theater. The only training I really had was David Mamet’s theater company, the Atlantic Theater company. And that’s all I did was go on these little stages and imagine things, but they were in small rooms so the difference is you still had to shout and project your voice, but everything was little bit bigger and the same with Robert, it’s very specific. He fine tunes your performance so its kind of a marriage of film and theater I felt.

Q: For the two of you, after doing all the work, can you talk about seeing yourself in that environment the first time; the first time you saw how the wizard put it all together for you, and can you also say if you've got a favorite scene from the movie?

BENICIO: : You know, it met the expectations when I saw the movie. Surpassed it. You know what happens when you're in a movie, for me, like I just do come in and work for five days, and I'm out. We just basically know one story. We usually look; when I see a movie, is the other stories that attract me more than my story. I'm looking at my story going, "Oh no ooooh". But, it's the other stories and; it's just hard to pick one moment. I really enjoy the under water stuff. I don't know, it was something about it. The movie has such a world that grabs you; it was a ride. You just took it and enjoyed it.

JESSICA: Yeah, I just felt like I was a little peak; a little line in this music, this piece of music that was beautiful like from beginning to end. I wanted to rewind it and see the whole thing all over again, cause I don't think I got to really like have all the images that I want in my mind. It's so much, you know, it was so visual and overwhelming and all the characters were so specific. And it's great.

"Sin City" opens in theaters everywhere today.
