"It ('Ungli') is not a typical Bollywood film," the 35-year-old said in an interview.
"(It is) A film having social relevance, along with other elements of society like corruption, where the common man is not able to raise his voice against corrupt powers and injustice happening to him and a gang, whose extreme measure is to fight injustice, comes to help him. I think this has rarely happened in our Bollywood films," he added.
Directed by Rensil D'Silva, "Ungli" is a fun take on the angst of today's youth and chronicles the story of five friends, who act as vigilantes against the corrupt powers and injustice.
There was perhaps no scope for music in the film, however, a special song "Dance Basanti" was shot for the film as it forms an important part of Hashmi's introductory scene in the film.
"There was no scope for music in the film but Rensil devoted one year finding music for it," said the actor, whose films are known to be packed with hit music.
"A song was needed for my introduction scene in the film and we needed a good song for that. So we thought of this track. It is a fantastic and catchy track. I loved shooting for it," he added.
"Ungli" also stars Kangana Ranaut, Sanjay Dutt, Randeep Hooda, Neha Dhupia and Neil Bhoopalam. It will hit the theatres Friday.
