Astronomer Nambi Narayan’s name pops up every time when the topic of discussion is space; he is a noted scientist and former aerospace engineer of the Indian Space Research Organisation (ISRO). Nambi Narayan is a key figure of the ISRO and recently a film has been made on his life titled ‘Rocketry: The Nambi Effect’. Celebrated actor R Madhavan has played the role of Nambi Narayan in this biographical film. Quite recently Madhavan visited Kolkata for the promotion of the film and interacted with the journalists. He said, “This is a very special film for me because besides acting in this film, I had to direct and produce. It is very important to tell the story of Nambi Narayan Sir to the people of the country. It is very important to know what case was going on against him and also to inform the people about his contributions. Also very few pictures have been made on the engineers and scientists of our country. That's why I made this picture". Along with R Madhavan, the film casts Bollywood king Shah Rukh Khan and southern film industry superstar Suriya in cameo roles. ‘Rocketry: The Nambi Effect’ released on the big screen on July 1.
