Robert Rodriguez is the ultimate filmmaker, and his gritty approach made him one of Quentin Tarantino's favorites. He's always had a passion for films, but "Sin City: A Dame To Kill For" is different. He was pretty much obsessed with it from way back.

The Red Bulletin has a tell-all interview with Rodriguez and they shared excerpts with Comic Book Movie. They feature the director as a film maverick who simply enjoys the art form:

"The closing credits of a Rodriguez film are thick with repetition: for Sin City 2, he's the co- director, producer, composer, cinematographer and editor. "My favorite hobbies growing up were photography, drawing, music, making movies," says Rodriguez. "I chose filmmaking because I could still keep all my favorite hobbies under the project of a film. So on all my early films, I did everything. And then as I got into the Hollywood system, I thought, 'I don't know why I should give up these things. They're still some of my favorite jobs.'"

But Sin City strikes a chord with him. It was a project that he absolutely needed to do!

"I would go to the comic book store, buy a Sin City, and go home and realize I already had three copies. I just loved it so much, and I knew nobody could ever make a movie out of it, because they would just ruin it."

Sin City, the graphic novel by Frank Miller, is not an easy material to ingest. It's dark and gory with a bluntness that borders on the offensive. Their world was populated by corrupt politicians, murderers, prostitutes, vengeful cops and their victims.

It was a challenge for Rodriguez to establish that look on the big screen. Only someone who has exhibited that much passion for the material can ever make an accurate interpretation.

Because it was the first venture, Rodriguez somehow held back:

"The first film, I didn't push it as far because I thought people wouldn't understand what they were looking at. It would be too distracting, it would be too strange. And then people thought it was visually groundbreaking. I was like, 'Oh my God, I didn't even go all the way with it.'"

The question is, did he go all the way with "Sin City: A Dame To Kill for?" Find out on August 22!
