Vidya Balan is known for her unconventional roles. Be it portraying Silk Smitha or being an enthusiastic Radio Jockey, the actress is a bundle of talent. And while she is set to enthral her fans with her mathematician avatar next, buzz suggests that Vidya has also signed up for another interesting role. Reports say the actress will be portraying the role of a forest officer in a film which will be based on Tigress Avni. The creature killed 13 people in Yavatmal’s Pandharkawda area and the man-eater was later killed by the authorities. If all goes well then Vidya will start work on this film soon after she wraps up ‘Shakuntala Devi: The Human Computer’.
