She went on to receive Filmfare Awards for Best Actress and Best Supporting Actress for her performances in the 2007 romantic comedy Jab We Met and the 2010 drama We Are Family, respectively.
Kapoor achieved further success by featuring as the female lead in two of India's top-grossing productions—the 2009 comedy-drama 3 Idiots and the 2015 social drama Bajrangi Bhaijaan—and received praise for her roles in the 2009 thriller Kurbaan and the 2012 drama Heroine.
The film, consisting of three chapters, tells the story of six individuals linked by a car accident.
Kapoor is featured in the third chapter as Oberoi's love interest (Mira, a witty young woman). Jha described her role as "fey and insubstantial", but further stated that "she turns these character traits to her own advantage to create a girl who is at once enigmatic and all-there".
Dubai-based actress Andria D'Souza was chosen to play the lead in the film, which was to be produced by Dimension Pictures.
Saif will soon start working on a multilingual horror-thriller film titled 'Hotel Red Rum', which will also be produced by Dimension Pictures. Telugu actress Archana Sastry aka Veda will essay the main lead in 'Hotel Red Rum', which will be made on the lines of 'The Texas Chainsaw Massacre'.
