2012 can well prove to be a comeback year for Rani Mukerji with films like Reema Kagti's Talaash and Anurag Kashyap’s <em>Aiyya</em> up her sleeve. In the Anurag Kashyap produced film, Rani plays a character who has a strong sense of smell. Her sense of smell is so strong that this quality helps her make some crucial decisions in life.
