Nayanthara (born Diana Mariam Kuriyan; 18 November 1984), is an Indian film actress who predominantly appears in South Indian films, primarily in Tamil.Nayanthara made her acting debut in the 2003 Malayalam film Manassinakkare with Jayaram. She made her debut in Tamil cinema with Ayya (2005) and Telugu with Lakshmi (2006). Both were successful. After this she had numerous commercially successful Tamil and Telugu films
While studying at college, Nayanthara worked part-time as a model. She was spotted by director Sathyan Anthikkad, who had seen some of her modelling assignments and approached her to play a pivotal role in his film Manassinakkare (2003). Although she turned down the offer initially, as she was not interested in films, she gave in eventually and agreed to do "just that one film". Manassinakkare went on to become a high financial success and she continued to receive acting offers. Both her releases in 2004, Natturajavu by Shaji Kailas, and Fazil's psychological thriller Vismayathumbathu, saw her co-starring alongside Mohanlal; while she played the protagonist's adopted sister in the former, she portrayed a ghost in the latter. Her performance in Vismayathumbathu, in particular, was lauded, with critics claiming that she had "stolen the thunder with her author-backed role",and was "the revelation of the film". She also acted in Thaskara Veeran and Rappakal.
She soon acquired the reputation of acting opposite male actors who are almost twice as old. She starred in her first Malyalam film opposite Jayaram, and then in "Chandramukhi" with renowned Indian actor Rajnikanth, then with other aging actors like Sarath Kumar, Mohanlal, and Mammotty.
She has been cast to play the lead role in a much younger Simbu's directorial debut, in which he also has the lead role. Nayanthara and Simbu's intimate life-sized posters created shock waves in Chennai, which were subsequently pulled down by the police. Similar excitement resulted when glamorous life-sized posters were posted all over Chennai
