Priyanka to play mentally-challenged girl

After creditably essaying seven looks in " 7 Khoon Maaf" and 12 different characters in "What's Your Raashee?", Priyanka Chopra will be seen as a mentally-challenged girl in her upcoming film " Barfee", which she describes as "by far the most challenging role".

"I have started shooting for the film, have shot nearly five days till now. I must admit that it is quite a difficult task," said Priyanka, who was here to unveil the wedding collection by jewellery brand Asmi for the ongoing The Great Indian Wedding Carnival.

"There is a very thin line between caricature and real. But surely, this role is by far the most challenging that I have come across," added the 28-year-old who is reportedly spending time in a mental asylum to get into the skin of the character.

The film is being directed by Anurag Basu and it features Ranbir Kapoor as a deaf and dumb person, while Ileana D'Cruz is set to play a narrator.
