“”Bye Bye Brown Hair” r u on viddy yet? I’m documenting my brown to Sin City blonde!” wrote Alba before getting her makeover.

“She got roots that Nancy #sincity2.”

But Alba isn’t just changing her hair color… She’s also getting physical for the role.

The following day, Alba shared a photo of herself during training lessons at the gun range.

“What a way to start the day -training for a movie is sorta fun,” she announced.

Sin City: A Dame to Kill For will focus on earlier story of Clive Owen‘s Dwight McCarthy, whose life is turned upside down when Ava, a woman from his past, returns and causes all sorts of problems for him.

Directed by Robert Rodriguez and Frank Miller, the film is slated for an October 4, 2013 release.

Alba’s co-stars include Mickey Rourke, Rosario Dawson and Michael Madsen.

Rodriguez to Make a “Sin City” Sequel

Robert Rodriguez is heading back to Sin City

The 43-year-old Mexican-American filmmaker and Frank Miller have announced plans to film a sequel to their 2005 cult classic Sin City, a film that explores the dark and miserable town, Basin City, and tells the story of three different people, all caught up in violent corruption.

Entitled Sin City: A Dame To Kill For, the upcoming film was developed by Miller from his graphic novel of the same name, and scripted by Miller and William Monahan. The film will be distributed once again by Dimension Films.

“Audiences have been clamoring for Sin City 2 with Robert and Frank for a long time and trust me, it will be worth the wait,” said Bob Weinstein, co-chairman of The Weinstein Company. “This will be my 11th collaboration with Robert in 16 years and he’s become a great friend. I look forward to continuing our long lasting relationship and partnering on more projects in the future.”

Production is slated to begin this summer at Rodriguez’s Troublemaker Studios in Austin, Texas with casting starting next week. According to the official release, much of the film’s original cast is expected to return— though the release didn’t specify if the characters who died in the first film would be popping up again.

Sin City, released on April 1, 2005, grossed over $160 million.
