Now, according to a report in Latestly, the film is being worked on the post-production stage and that Shah Rukh Khan is involvement in the project. The source said, "Shah Rukh Khan has shot most of his part for the Hindi version and he is seen sharing the screen with R Madhavan, playing a 77-year-old Nambi Narayanan, who narrates his side of the story. It looks like Shah Rukh Khan's role in the film might be of an interviewer, who is interested to know more about Nambi. The rest of the film will go in flashback mode." The source added that while SRK may be interviewing Nambi, he doesn't look like he belonged to the field of media, because the scene didn't involve any mike or tape recorder.
