Rocketry: The Nambi Effect is an upcoming biopic based on the life of Nambi Narayanan, a former scientist and aerospace engineer of the Indian Space Research Organisation, who was falsely accused of espionage. The film is written, produced and directed by R. Madhavan will be making his directorial debut with this film. Madhavan will also be starring in his film in the titular role that he has written and produced as well. The story covers Narayanan's days as a graduate student at Princeton University, before exploring his work as a scientist and the false espionage charges placed upon him.
Madhavan is very overwhelmed by the immense support he is getting from his fellow peers in the industry. Both Suriya and Shah Rukh Khan who are playing an important role in the film's Tamil and Hindi version respectively, did not charge Madhavan anything for their involvement in the film. They were more than happy to do it for free, which not many actors of such high position are willing to do.
During a press conference, he said, "Be it Suriya or (Shah Rukh) Khan sahab, none of them charge any fee for the film. They didn't even charge anything for the caravans, costumes, and assistants. Suriya flew out to shoot in Mumbai along with his crew on his own money. He didn't even charge for the flights or for the dialogue writer who translated his lines in Tamil."
While on the promotional tour for his debut film, R. Madhavan revealed that he received a lot of support from Bollywood actors for the film. The actor, writer, director, and producer carried a lot of gratitude towards megastar Amitabh Bachchan and Priyanka Chopra Jonas for extending their support to his film via social media. During that same press conference, Madhavan revealed, "There are a lot of good people in the film industry. But, I am from outside. People have helped me a lot. Just on my request Amit ji (Amitabh Bachchan) or Priyanka Chopra posted a tweet (to support the film). I am grateful for their love and respect towards me”.
