Shah Rukh Khan may not have a full-fledged movie to work in as of now, but the actor was busy preparing for his cameo in R Madhavan’s ‘Rocketry: The Nambi Effect’. It has been revealed that Badshah Khan will interview Madhavan’s character of ISRO (Indian Space Research Organisation) scientist Nambi Narayanan where the latter will be narrating his story to SRK. The film, hence, will run in flashback. Shah Rukh has acted in the Hindi version of ‘Rocketry: The Nambi Effect’ but has not essentially played a media person or a journalist interviewing Maddy, those in the know say. ‘Rocketry: The Nambi Effect’ is the story of the controversial scientist and aerospace engineer Nambi Narayanan, who came under the cloud of espionage but was later cleared from the Supreme Court of India.
