Latha was initially chosen to portray Jayachitra's sister; however a day before the film's launch, she informed she could not act in the film. During the launch, the producers announced that Jayachitra will play dual roles as siblings. The film's launch saw T. R.

The soundtrack was composed by Vijaya Bhaskar.
