Aishwarya revealed that she had written the script with Shruti Haasan in mind, but date problems meant that the film began its shoot with Amala Paul instead.
However, in a turn of events, Shruti was re-signed to play the character of Janani, and the film gained much hype prior to release due to the collaboration of herself and Aishwarya, being the daughters of the two leading contemporary Tamil actors Kamal Haasan and Rajinikanth, as did the success of the song "Why This Kolaveri Di? The film opened in March 2012 to positive reviews, with a critic noting: "Shruti Hassan has come a long way", though the film only garnered average returns at the box office.

Through her career, she has received three Filmfare Awards and has established herself as one of the leading actresses of South Indian cinema.In a recent poll conducted by the Chennai Times, Haasan topped the list of most desirable women.The film went on to become a major commercial success at the box office and brought in more film offers for Haasan.The films emerged as moderate successes and Haasan received generally positive reviews for her performances.After several successful films such as Gabbar Singh (2012), Vedalam (2015), Srimanthudu (2015) and Singam 3 (2017), she established herself as one of the leading contemporary actresses in Tamil and Telugu cinema.
Alongside appearing in Tamil and Telugu films, she has also appeared in several commercially successful Hindi films, including Ramaiya Vastavaiya (2013), Gabbar Is Back (2015) and Welcome Back (2015).Shruti Haasan has recently been honored with life membership of the International Film And Television Club of Asian Academy of Film & Television by Sandeep Marwah.Shruti Haasan was next seen in Aishwarya Dhanush's directorial debut 3, a romantic drama film co-starring Dhanush.The film portrayed her as Nikki Narang, the step-daughter of an ex Miss India model, with Hashmi's character falling for both mother and daughter.Shruti's performance gained poor responses from critics with a reviewer citing that her character has been "reduced to post-interval surfacing, last-ditch glamour", whilst another labelled hers as "so fake that she offers only disappointment"; Shruti played Subha Srinivasan, a young scientist in the film, who hopes to re-activate the genes of 5th century Buddhist monk Bodhidharma, and her performance in the film won appreciation from critics.As a child artist, she sang in films and appeared in a guest role in her father's Hey Ram (2000), before making her adult acting debut in the 2009 Bollywood film, the drama thriller film Luck.
