This was Rani Mukerji's first appearance in a movie produced by Yash Raj Films after her marriage to producer Aditya Chopra.
Rani Mukerji's character in the film was inspired by real-life police officers Jyotsana Rasam and Meeran Chadha Borwankar. The two police officers were consulted for the film and were acknowledged in its opening credits.[2]
