R Madhavan plays Nambi Narayanan, a former scientist of the Indian Space Research Organisation who was accused of espionage, in Rocketry: The Nambi Effect. In an interview with NDTV, Madhavan said that he wanted to showcase the ex-ISRO scientist's achievements. "After meeting Nambi sir, I realised, the biggest disservice to the nation was not to know about what Nambi sir's contribution was. I chose to take the path of highlighting Nambi sir's achievement which was not being done till now," he said.
