Movie Forum: From 'Spy Kids' to 'Sin City'

Robert Rodriguez: I'd love to do a romantic comedy. My favorites are "What's Up Doc?" and "Some Like It Hot."

London, England: What are the technical challenges for a self-taught hands-on filmmaker like yourself in making a movie like "Sin City," which is so reliant upon CGI?

Robert Rodriguez: I self taught myself CG a number of years ago, because I could see that was where the industry was going. It's good to be versed in all technologies, it really gives you the freedom to create anything. By knowing effects, I can make a movie like "Sin City" very guerrilla style, where people tend to think that effects movies take a lot of planning. When you know effects and CG you can make up shots on the spot and really improvise.

Santa Clara, CA: Hello Robert, I am waiting with great anticipation for this watershed of a movie. One question, very interesting casting choice (and one the I love wholeheartedly BTW) was casting decidedly British actor Clive Owen as Dwight. What was the impetus for such a choice?

Robert Rodriguez: It was hard to find someone that was a good physical and character match for Dwight. I've always wanted to work with Clive, and showed Frank the John Woo-directed BMW short film on the Internet. I said, "This is the guy I think is Dwight." Frank said, "If you think it's him, cast him, you've been right so far ... " It was a leap because I had never met Clive, but there was something in that short that made me believe he was the guy. People say I have a good eye for casting, but I've usually found it to be more of a gut feeling than a visual impression.

Dallas, TX: My daughter and I really enjoyed your "Spy Kids" series ... will there be more? Will you be making more movies geared toward kids? We sure hope so.
