What is "navarathri"

Navarathri ("Nine Nights") is a 1964 Tamil Drama film by A. P. Nagarajan. The film is well known for starring Sivaji Ganesan in nine distinct roles: the basic emotions - wonder, fear, compassion, anger, peace, love, courage, repulsion and happiness. It was Sivaji's 100th film he acted. Navarathri traces Nalina's ( Savitri) experience of these nine emotions on nine consecutive nights. The record of playing most number of roles in one Tamil film was long held by Sivaji Ganesan until 2008 when it was broken by Kamal Haasan in Dasavathaaram (2008). In 1966, the film was remade in Telugu with the same title and in Hindi as Naya Din Nai Raat (1974)with Sanjeev Kumar.
