Jessica Alba has revealed she worked hard to master complicated new dance routines for the Sin City sequel.
The US actress, who performed a raunchy routine in the first film, admitted she needed three months training before she reprised her role as exotic dancer Nancy Callahan in Robert Rodriguez's follow-up, A Dame To Kill For.
"I had to learn a bunch of dance sequences for it. I do a lot more dancing in this one. It was kind of crazy. It was very, very difficult, and you'll see why," she told Vulture.
Jessica will star alongside Josh Brolin, Mickey Rourke and Joseph Gordon-Levitt in the upcomimg movie, which is scheduled for an October release in the US.
