Actress Rani Mukerji on Monday unveiled ‘Mardaani’ anthem and says it talks about “anger and frustration” women go through. “This anthem is a thought that has come from the anger and frustration we go through in our daily life,” Rani told reporters. “The anthem is written by Kausar Munir. This anthem is beautifully depicted. The lyrics are very powerful,” added the actress. Director Pradeep Sarkar’s film Mardaani will see Rani as Shivani Shivaji Roy, an officer of the Mumbai Crime Branch unit. In the raw and gritty tale, Rani displays women power. She said: “Men are physically strong but women are mentally and emotionally strong. There is nothing man can do without women.” Produced by Rani’s husband Aditya Chopra of Yash Raj Films (YRF) banner, Mardaani is slated to release on Aug 22.
