Priyanka Chopra, who plays an autistic girl in Barfi!, says she is game for such tough roles.
Asked how she chooses such tough roles one after the other, Priyanka said: "Whichever role is the toughest, bring it to me, I'll do it."
She has played challenging roles in 7 Khoon Maaf, Fashion, and Kaminey.
Her forthcoming Barfi! spreads the message of being happy in any state, just the way the lead character Barfi, essayed by Ranbir Kapoor, does despite being deaf and mute.
"We have brought 'Barfi!' to spread happiness. The film's philosophy is 'Don't worry, be Barfi' instead of 'Don't worry, be happy' we are saying this," the 30-year-old said here.
"Ranbir's character's philosophy is this! When he enters our lives, he touches us all and teaches us that you don't need much to be happy, just a big heart," she added.
"Barfi!" also features Telugu actress Ileana D'Cruz. It is slated to release Sep 14.
