Jessica Alba insists some of her 'Sin City: A Dame to Kill For' alter-ego's dance routines are ''kind of crazy'' in the sequel to 2005's 'Sin City', meaning she had to endure some ''very difficult'' dance training for the role.
Jessica Alba has endured some ''very difficult'' dance training for her 'Sin City: A Dame to Kill For' role.
The 31-year-old star is to reprise her role as exotic dancer Nancy Callahan in the forthcoming thriller sequel to 2005's 'Sin City', and the screen beauty insists some of her alter-ego's routines are ''kind of crazy''.
She told Vulture magazine: ''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.''
While Jessica - who has two daughters, Honor, four, and 17-month-old Haven - took on additional training for her dancing scenes, she insisted on a body double for her stripping role.
A source recently said: ''She was crushed when filming began and she didn't have her original body back so she told producers she wanted a body double.
''Her body is incredible, but for her it's not good enough.''
