Lang is a 2015 Indian Tamil-language comedy drama film directed by Ramesh Aravind and written by Kamal Haasan, who co-produced the film with Chandrahasan under Raaj Kamal Films International and N. Lingusamy and N. Subash Chandrabose under Thirrupathi Brothers. The film features an ensemble cast that includes Hassan, K. Viswanath, K. Balachander (in his posthumous film), Jayaram, Andrea Jeremiah, Pooja Kumar, Nassar, Parvathy Thiruvothu and Urvashi in prominent roles. In the film, a leading superstar, who is affected by a brain tumour and having a short time to live, approaches his mentor to direct his final film—a folklore-ish comedy about a man who keeps cheating death and his role in saving a kingdom—while also trying to sort out his personal relationship with his estranged son and illegitimate daughter.

Plot

Manoranjan is a leading film star who is immensely popular among his fans but is beset with several personal problems. Twenty-five years ago, he had been forced to marry Varalakshmi, the daughter of noted film director Poornachandra Rao, despite being in a relationship with a woman named Yamini (not shown on-screen). His relationship with his son with Varalakshmi, Manohar, is troubled. Besides, he comes to realise that he has a daughter Manonmani, who was born out of wedlock, during his relationship with Yamini, and was raised by Yamini's husband Jacob Zachariah, after Yamini's death. Furthermore, he is recently diagnosed with advanced stage brain cancer and has only a few more months to live, a fact which is unknown to his own family. He is treated by his family doctor Dr. Arpana, with whom he has an extramarital affair.
