Jennifer “JJ” Johnson, who also choreographed the dance sequences in the movie, would get together with Alba for sessions that ran 2-5 hours at a time and, according to the instructor, included “crawling, arching, humping … winding, grinding and moving.” _Sin City: A Dame to Kill For_ is set for release on August, 2014. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/135922/jessica-alba-sin-city/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/135922/jessica-alba-sin-city/"},"headline":"How Jessica Alba Got In Shape for the New Sin City Movie","datePublished":"2014-05-29T14:56:47.000Z","dateModified":"2026-02-21T08:06:28.683Z","description":"Nancy Callahan will be fiercer than ever, thanks to this dance instructor.","url":"https://time.com/135922/jessica-alba-sin-city/","keywords":["movies","celebrities"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blte776e4c05d10116b/69869142f983e7163604e046/jessica-alba2.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"TIME Video","jobTitle":null,"url":"https://time.com/author/time-video/"}],"articleSection":"Entertainment","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blte776e4c05d10116b/69869142f983e7163604e046/jessica-alba2.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"The Helping Hand Of Los Angeles Mother's Day Luncheon","caption":"The Helping Hand Of Los Angeles Mother's Day Luncheon","creditText":"Jon Kopaloff—FilmMagic/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/entertainment/","name":"Entertainment"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/movies/","name":"movies"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/135922/jessica-alba-sin-city/","name":"How Jessica Alba Got In Shape for the New Sin City Movie"}}]}] ```
