Sana Khan, famously known as one of the participants in Big Boss Season 6, started her career with a low budget Hindi film
Yehi Hai High Society (2005).
After this she consistently started doing various television commercials. With the controversy of Amul Macho ad, she chose to move on.
She continued doing dance numbers in both Hindi & Tamil films. Famous one being the Billo Rani from Dhan Dhana Dhan Goal (2007).
After this she made her debut as a lead actress in the Tamil movie
Silambattam (2008) & instantly won the hearts of the viewers with her glamorous act & graceful dance moves. Despite negative reviews, Silambattam went onto become a successful venture making her noticed in the south Industry. She won the ITFA Best New Actress Award.
Here's one of the famous songs from the movie Silambattam with Simbu & Sana at their dancing best.
After Silambattam, she played a role in Ajay Devgn starrer
Halla Bol. Her another attempt at making a mark in Bollywood was not fruitful. So she concentrated more on the Southern films. Her next Tamil film Thambikku Indha Ooru (2010) & Telugu film Kalyan Ram Kathi (2010), both ended up as box office failures. This was followed by critically acclaimed Tamil-Telugu bi-lingual starring Nagarjuna & Prakash Raj, Payanam / Gaganam in 2011 which gave her much relief as far as box office numbers are concerned. All these films have been dubbed to Hindi.
Before getting selected as a contestant for Big Boss Season 6, she did 3 more films,
Kool... Sakkath Hot Maga (2011) through which she debuted in Kannada films. Followed by a Tamil film Aayiram Vilakku (2011) again a critically acclaimed film & Telugu commercial potboiler Mr.Nookayya (2012) previously titled Mr.Nokia which had to be changed for legal issues. All these 3 films failed at the box office.
After getting much more fame through Big Boss, she ventured into Malayalam film industry with the movie
Climax (2013). It was her attempt of pulling of a Dirty Picture, as the film was based on Silk Smitha's life. But her attempt ended up being a bad one, she couldn't pull off a Vidya Balan, movie opened to terrible reviews & bombed at the box office.
So finally as promised by Salman Khan, she was offered
Jai Ho which she took it. She'll be seen in a negative role previously donned by actress Ravali in the Telugu original successfully. Hoping to change her luck with the biggest film of her career.
