Tamannaah's first release of 2009 was the Tamil film Padikkadavan, directed by Suraj and co-starring Dhanush, which was named after Rajinikanth's 1985 film of the same name. The film received mixed reviews from critics, but Tamannaah's performance in a limited role won praise. Padikkadavan however, became a commercial success. Her next release was the Telugu film Konchem Ishtam Konchem Kashtam, directed by Kishore Kumar Pardasany, co-starring Siddharth. The film received positive reviews from critics and she received critical acclaim for her performance, earning a nomination at the 57th Filmfare Awards South in the Best Telugu Actress category. The film, however, was an average grosser at the box office. Her next release, K. V. Anand's Ayan, co-starring Suriya, became the only major commercially successful Tamil film of the year. She later appeared in Gandhi Krishna's Ananda Thandavam, which was based on the novel Pirivom Santhippom serialised by Sujatha Rangarajan. She was paired with Siddharth Venugopal in the film, marking the latter's debut. The film opened to negative reviews, and was her only commercial failure in 2009. However, Tamannaah's performance was critically acclaimed. Pavithra Srinivasan of Rediff. com stated that Tamannaah's "would-be innocence when she's playing up to Sidharth, and slight cunning when she chooses Radhakrishnan is perfect" adding that she brought her character Madhumitha "to life, an alluring mix of child and woman; irritating, sly, yet arousing your sympathy in the climax".
