"Shekhar Subramanium is the real character, who is the father in the film Ra.One. We wanted to play south Indians - little bit of caricature. He is a Tamilian, he will have curly hair and he is man with golden heart. He believes in goodness. He is goofy, geeky and he is a software engineer and a game designer. He believes that goodness is the best thing human beings can have."
"On the other hand to play G.One, what I had to do was obviously have two different looks, which was completely opposite.The body was most inline and stomach and physique have been worked upon so that you can have six packs and look like sterdy and dudey. The hair is straight, focused straight and blue eyes."
"Shekhar is little dark, while G.One is fair. So we wanted it to be completely contrasting in physicality. Shekhar is animated over the top, while G.One is very straight and quiet, unidimentional in acting because he is a machine. As an actor, I wanted only thing to do is that the innocence in Shekhar should be captured in G.One."
"I wanted the toughest not to overpower the innocent and child like quality of this machine or a virtual person. It was interesting to play both. One is geeky clumsy and one supposedly graceful and straight forward. It was nice to play that quite dichotomous and different for an actor to do in one film."
