"If Ranbir wouldn't have done this movie, I wouldn't have made it. I always had Ranbir in my mind for this role. Even on the day when I was writing the 10th page of the script," Basu said in a statement here.
Ranbir essays the role of a deaf and mute person and he excels with his intricate gestures and body language, which reminds one of Mr Beans and Charlie Chaplin.
"Ranbir as a person is very spontaneous and naughty. His aura is such that I remember on the last day of shoot, Ranbir was bidding good bye to all by hugging them. I saw how everyone was feeling that moment....they were really feeling sad," Basu said.
"I don't know if it was RK or Barfi who created that feeling in all," he said.
Releasing on September 14, Barfi also stars Priyanka Chopra, who plays an autistic character in the film besides Tollywood actress Ileana D'Cruz.
