The 23-year-old actress will be playing an Interpol officer in director Abhay Deol's The Game, the The Times of India has reported.
Ranaut told the paper: "It was challenging to prepare for this role of a British girl from London who is actually quite like a man in many ways."
According to the star, producers Ritesh Sidhwani and Farhan Akhtar were initially planning to cast a man in the role.
"I had to make sure that I got the body language perfect. There is nothing romantic or sensual about this Interpol officer. Yet my director didn't want to go overboard with the stiffness and appear like too masculine," she added.
