A source reveals, "Hrithik underwent training and met various paraplegic patients to get into the skin of his character. The actor is on the wheelchair for a major portion of the movie. He used to practice around in his house on the wheel chair and also had read and gone through booklets and guides which gave him information about the physical behavior of such patients."
Hrithik has grown his hair really long and also has his beard grown. While making public appearances he normally gels up his facial fuzz but has the long hair look.
"Neither Hrithik nor his director wanted to make use of any artificial hair. They wanted to have a natural look and one will see Hrithik with this look till the shooting is on for the movie," adds the source.
