Shah Rukh Khan plays a South Indian in the film but he is buried according to Catholic rites and then its shown his ashes are poured into lake as per Hindu rituals if he was buried from did his ashes come.
The idea of making Ra.One originated while he was watching a commercial on TV six years ago. Sinha said, "The commercial dealt with two kids controlling a human with a remote. It was fascinating, and the visual stayed with me for some time." Sinha wrote a three-page short story based on the commercial, which he felt was good enough to be made into a film.
To reports of similarities with other films Khan responded with "I got inspired from a lot of superhero movies but the movie is original. In fact, Ra.One will be the first superhero-based movie in the world in which the superhero lives in a family."
