Anushka Sharma who is gearing up for the release of the forthcoming film, 'Zero' says the challenge of playing the role suffering from cerebral palsy excited her for the film. 

The actress in a statement revealed she went through a rigorous three-month preparation process for the role.

"I understood the challenge that I was going to face as an actor while playing this role. That is what excited me towards the role. If I were able to pull it off, I would have accomplished something. So I wanted to do it the right way and represent this correctly. 

Aanand sir and Himanshu (writer Himanshu Sharma) had already researched a lot with doctors (about this condition) when they came to me with the film and had sketched out my character accordingly. I understood their brief and went with their vision and met with the doctors,"

Anushka who will be seen sharing screen space with Shah Rukh Khan as a dwarf, worked with an occupational therapist and audiologist to understand the physical limitation of her character and how the condition would impact her speech.

Talking about the difficulties she faced when the shoot began, Anushka said, "The difficult part in this was that I had to voluntarily create an involuntary movement that happens to my character because of my condition. While I had to focus on the dialogues, I also had to focus on the emotion of the scene, which was difficult. So, in the beginning, I would ask for some extra takes so that I could get it right because I wanted to make sure that I was doing it correctly,".

Sharma onscreen will be seen playing a character that suffers from cerebral palsy and is in a wheelchair. It meant she had to spend a lot of time on a wheelchair offscreen as well.
