O Kadhal Kanmani is a 2015 Indian Tamil-language musical romantic drama film written, directed and produced by Mani Ratnam.
The film stars Dulquer Salmaan and Nithya Menon as Adhi and Tara, two individuals who share a common dislike for marriage. They begin a live-in relationship in Mumbai, but must eventually confront the question of whether to continue or move forward together.
Prakash Raj and Leela Samson play supporting roles as an older couple in the film, portraying the younger couple's landlords. The story explores themes of modern urban India, including marriage and traditional values.
The film features music composed by A. R. Rahman, cinematography by P. C. Sreeram, and editing by Sreekar Prasad. The title is borrowed from the song 'Pottu Vaitha Kaadhal Thittam' from Kamal Haasan's 1992 film Singaaravelan.
