The film, though, is not based solely on the Delhi incident in which a 23-year-old medical student died after bring brutally gang-raped in a moving bus, he said.
"Even though a small portion of the film will revolve around the incident, it is not entirely about it," Mr Gaddam said.
Nisha is produced by J Dhanraj Goldee, Sunny and Pranay Kumar have composed music.
The film, currently in post-production phase, stars Kiran Kumar, Ananya, Kalyan and Narsing in lead roles.
