R Madhavan is donning multiple hats for Rocketry: The Nambi Effect. He is acting, directing, wriing the story, lyrics and producing the film. At the press meet of Rocketry, Madhavan revealed how he wrote the script of Rocketry.
Madhavan said, "After the completion of Vikram Vedha, my friend suggested me to make a movie based on real incidents that happened in the life of an ISRO scientist, who was falsely accused of revealing the National secret to the Pakistan army, was tortured in prison almost to death, but he came out and proved his innocence. Initially, I was excited about this idea as it gave me an impression of a James Bond-styled flick. Brimming with my assumptions, I met Nambi Narayanan, which changed my dimension of life. To be precise, I would categorize my life as Madhavan before and after meeting Nambi Narayanan. I had known that he is one of the intelligent minds of India, but when I met him, I could see an adorable aura in him. His lips were shivering with anger and worries, which had lots to speak. When he started recalling the injustice done to him, he almost got high-tempered, and I had wanted to cool him down. I said, “Sir, Let bygones be bygones. You’ve been acquitted on all charges. I think there’s nothing to worry about now.” But he reverted stating, “Yes, it’s true that I have been proved innocent by court and police, but you Google my name and you’ll see ‘Spy’ tagged to it. My family has been branded in such a way, and it remains irreversible.” This instantly instilled in me, the urge to write the script. "
