Agni Natchathiram (English: Star of Fire) is a 1988 Tamil film directed by Mani Ratnam. The movie is about two half-brothers who come into conflict with each other in their claim for legitimacy as sons of a common father. Prabhu and Karthik play the lead roles. The movie's score and soundtrack are composed by Ilaiyaraaja. The film was a blockbuster and completed a 200-day run at the box office.
The film was dubbed into Telugu with the title Gharshana (not to be confused with the 2004 Telugu film of the same name), and was remade in Hindi as Vansh starring Siddharth Ray and Sudesh Berry.
