Rani Mukerji launched an anthem song of Mardaani which is a special promotional 
video that has been shot for the film
The song has bold and powerful lyrics written by Kausar Munir.
The anthem talks about the various things women go thorough and talks about how they should stand up for themselves and fight back.
Rani encouragingly spoke about how women should stand up for themselves. She also spoke about the training she underwent to get into the skin of her character.
Pradeep Sarkar, the director spoke about how Rani has portrayed the character of officer, Shivani Shivaji Roy flawlessly and how we should all collectively act, rather than attending candle marches.
Also present at the event was the lyricist Kausar Munir and script writer Gopi Put

Mardaani Anthem is extremely powerful in its rendition. Supported by stark visuals, foot tapping and hard hitting lyrics, it’s a song that has potential to influence.
Kausir Munir says, I watched the film before I wrote the lyrics. And I felt that we needed a song that spoke about the inherent strength and grit of a woman. While we may be weak physically we are not weak as people.
This is first YRF film that has no song… Mardaani Anthem is a promotional song.
