Sin City writer Frank Miller is delaying plans for a follow up film, because the original movie lead to an influx of job offers.

Miller, 48, has been so inundated with work since the film's release earlier this year, he is finding it difficult to make time for a sequel, despite having numerous plot ideas.

Jessica Alba, who played Nancy in Sin City, says, "I talked to (director) Robert Rodriguez, and he's doing some movie with Quentin Tarantino called Grind House."

"He wants to do Sin City 2 after that, but Frank is like a big Hollywood star now. I had dinner with him, and he has some cool ideas about Nancy."

"He might work on the graphic novel and then release it simultaneously."
