character. But he changed his mind and offered her the role after seeing her audition tape. The film met with generally positive reviews and was a box office success. Koechlin garnered praise and a Filmfare Award for Best Supporting Actress for her performance, which was described as "imbued [...] with a touching fragility" and "astonishingly [appropriate]". Others were more impressed by her character's complexity, but thought of Koechlin's performance in the film's first half as amateurish. Koechlin played a supporting role in the black comedy The Film Emotional Atyachar, her only film appearance of 2010. Co-starring Ranvir Shorey, Mohit Ahlawat, Abhimanyu Singh, Vinay Pathak, and Ravi Kishan, the production opened to mixed reviews. Her performance as Sophie, a manipulative woman who is abducted by two corrupt policemen, garnered mixed reviews from critics. Komal Nahta of Koimoi labelled her performance as average, while Blessyy Chettiar of Daily News and Analysis felt that she was underused. Koechlin had committed to star in I am Afia, one of the four short films of Onir's anthology I Am, but it went into production with a modified plot for the segment. In an interview with The Telegraph Onir said, "as we discussed the subject more and more, both Kalki and me felt that the narrative was becoming too hurried in the 25-minute limit". Koechlin, who was to play the role of an NGO worker in the film was ultimately replaced by Nandita Das, after the change of plot. Breakthrough and commercial success (2011–2014) After facing some early struggle for film roles, Koechlin had four releases in 2011, garnering widespread recognition for her performances in them. The first was Bejoy Nambiar's Shaitan, a crime-thriller with an ensemble cast that included Koechlin, Rajeev Khandelwal, Gulshan Devaiya, Shiv Panditt, Neil Bhoopalam, and Kirti Kulhari. She played the role of a disturbed teenager and called it an exhausting experience, saying that she felt drained while trying to, "get into a psyche of someone who does a lot of drugs and booze, has lost her mind a little bit and is very vulnerable". While the character was inconsistently described by film critics as "nightmarish" and "engaging", Koechlin was praised for her performance, with Raja Sen calling her "an increasingly striking actress". Upon release, the film received positive reviews from critics, and earned Koechlin a Screen Award for Best Actress nomination. Koechlin then starred in Zoya Akhtar's coming-of-age romantic comedy-drama Zindagi
