Duet is a 1994 Indian Tamil-language romantic musical film written and directed by K. Balachander.

The film stars Prabhu, Ramesh Aravind, Meenakshi Seshadri and marks the debut of Prakash Raj in Tamil cinema which he plays the antagonist.

It was inspired by the 1990 French film Cyrano de Bergerac, which itself was based on the 1897 play of the same name directed by Edmond Rostand.

Guna as a saxophone player, music director, and lyricist and Siva as a singer flourish in their career.

To make Anjali fall in love with him, Siva lies to her that he has all the talents of his brother.

Guna, who feels inferior about his fat size, decides to begin a friendship with Anjali's father and gradually with her, unaware of the fact that she already loves Siva.

Anjali responds to his indirect approach, thinking that it is done by Siva, but Guna is very happy that she loves him.

Film superstar Sirpy also gets attracted to Anjali and behaves very close with her, which irritates the possessive Siva.

Anjali also learns that Siva has lied to her about his saxophone and poem writing talent and gets furious on him.

Angry Sirpy gives a fake statement to the press that both himself and Anjali are in love and planned to get married shortly.

Back to the present, it was the day when Siva died on the same place where Guna is playing saxophone on his memory.

Vijiyan of New Straits Times wrote, "It is a simple story but Balachander's screenplay and handling of the cast make it memorable".

[11] R. P. R. of Kalki praised Kadri Gopalnath's saxophone work, art direction and cinematography but panned the humour and the fight scenes calling them dark spots.
