Rocketry: The Nambi Effect is a 2022 Indian biographical drama film written, produced and directed by R. Madhavan in his directorial debut. The film is based on the life of Nambi Narayanan, played by Madhavan, a scientist at the Indian Space Research Organisation, who was accused in the ISRO espionage case and later exonerated. The story spans across 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.

After its official announcement in October 2018, principal photography took place across several countries including India, Russia and France. The cinematography and editing were handled by Sirsha Ray and Bijith Bala, respectively, while the original score is composed by +more_S. '>Sam C. S. Rocketry was filmed simultaneously in the English, Hindi and Tamil languages.

Rocketry premiered at the 2022 Cannes Film Festival on 19 May, and was theatrically released in India on 1 July 2022. The film opened to mostly positive reviews from critics, who praised Madhavan's performance, his screenplay and his noble intention to make the film.



During the present time in a televised interview with actor Shah Rukh Khan (Hindi)/Suriya (Tamil), Nambi walks through the events leading to his rise as an eminent engineer to alleged espionage charges, physical and mental cruelty against him.

Nambi starts with his experiences at the Thumba Equatorial Rocket Launching Station, where he saves +more_J. _Abdul_Kalam'>A. P. J. Abdul Kalam, one of his team members from a major injury during an experiment. In 1969, he is accepted into Princeton University in the US.

Nambi successfully completes his MSE program in chemical rocket propulsion under professor Luigi Crocco who recommends him for the NASA fellowship. However, after a brief stint at NASA with Barry Amaldev, he is offered a generous paycheck and other allowances. +more He rejects it and returns to India so that he may make use of his talents at ISRO. Subsequently, he also manages to get 400 million pounds of equipment from Scotland for free. However, after the suspicious death of Vikram Sarabhai, he did not have adequate support from ISRO or funds from the Indian government to continue his research.

At this point, Nambi strikes a deal with the French who need skilled scientists to help them build their own liquid fuel engine. He then moves to France with his colleagues, hoping to learn from France's advanced technology so that they may recreate it back in India. +more Unbeknownst to the French, Nambi and his 52 colleagues have learnt French before their journey but pretend to not understand them. After being kept out of their major discussions, Nambi's team tries to find a way to gain access to these meetings and test data. It is then that they discover that the French engine is faulty. Nambi uses this opportunity to gain access to the required data in exchange for fixing the engine. The team then returns to India and start working on building their own engine on liquid fuels. However, due to lack of resources, it takes 8 more years to complete. They test the engine at the same testing facility in France - it goes above the 135 pressure mark, and goes all the way to 180. Successful in his plans, Nambi returns to India after naming the engine VIKAS after Vikram Sarabhai, his mentor.

Nambi's focus is now on cryogenic engines which he believes will make India competent to participate in the world satellite market. Knowing ISRO's limitations in terms of time and resources, Nambi decides to purchase these engines from some other country. +more He strikes a deal with Russia (then USSR) after informing them that he knows about their cryogenic missiles, told to him by his Russian friend in Princeton. He requests 4 of them to be imported to India. After the Russians agree, the Americans find out about this deal and try their best to break it. While USSR is on the brink of collapse, Nambi and his colleagues manage to expedite the transfer process and sneak out a couple of engines from under the Americans' nose with the help of the Russians.

Back in India, Nambi is arrested out of the blue while news of his treason spreads like wildfire. He is taken to a guest house in Trivandrum where he is beaten and tortured in an attempt to make him confess to his alleged crimes. +more He also recognizes that the officials are trying to make him repeat their sentences and that there is a recording device in the room to capture it. However, Nambi holds his ground and denies all charges. It was alleged that Nambi met Mariam, a Maldivian woman, in a hotel in Chennai and after being caught in her trap, he was forced to sell India's rocketry secrets to Pakistan. After being hospitalized due to his injuries, Nambi is met by CBI official P. M. Nair, who thoroughly investigates the matter. Nair brings Mariam and her friend, along with a few others into the room. Mariam and her friend reveal that the Kerala police officer in charge of the investigation, Gopal, tortured and threatened them and made them falsely incriminate Nambi, whom they have never met before. They also apologize to Nambi for ruining his reputation and causing pain to him and his family. Nair also figures out that all the accused in this case were members of ISRO's cryogenic wing, and concludes that it was a huge ploy by some powerful parties to hinder India's progress in the cryogenic sector.

Months later, Nambi receives bail and returns to his house to find his family members traumatized by the way they were treated by others. Nambi's wife Meena is in need of psychiatric help and the rest of his family are still shunned by the society. +more Hence, Nambi decides that he has to clear his name so that his family may lead normal lives in the future. Years later, Nambi is proven innocent by the Supreme Court and returns to ISRO, helping his colleagues with the Mangalyaan mission. Nambi is later awarded the Padma Bhushan for his contributions to Indian Space Research.

After hearing his story, Shahrukh Khan (Hindi)/Suriya (Tamil) feels so bad for Nambi, that he apologizes to Nambi on the behalf of the whole nation, as the interview ends.

A film based on the espionage case of Indian Space Research Organisation (ISRO) scientist Nambi Narayanan was first announced to the media in September 2012 by director Anant Mahadevan. Journalist +more_P. _Surendran'>C. P. Surendran had proposed the idea for a potential film on Narayanan to Mahadevan during June 2012. The two then met Narayanan in person to discuss the idea and seek his permission, and he agreed to serve as a consultant for the project. Malayalam actor Mohanlal was cast in the role of Narayanan, while Resul Pookutty, Sreekar Prasad and L. Subramaniam were finalised as the sound designer, editor and music composer for the project. Titled The Witch Hunt, the film was to be made in the Hindi and Malayalam languages. The team were in talks with several production houses but the project eventually did not take off as planned. Mahadevan later narrated the idea of the film to actor R. Madhavan in the mid-2010s, who helped take the film forward.

Work on Rocketry: The Nambi Effect was first reported by Madhavan in the media during April 2017, when he announced that he was set to appear in a biopic featuring the "extraordinary story of an unsung hero", who was "neither an actor nor a sportsman". He called the project his "biggest film ever" and stated that he had worked silently on the script of the film for a period of two years after becoming intrigued by hearing the tale of Narayanan's false espionage charge. +more To develop the script and to provide a more factual account of the events, Madhavan regularly met with Narayanan, garnering his approval for the film and discussing the scientist's life experiences. As a result of their conversations, Madhavan chose to alter his original script to include portions from Narayanan's entire career and his services to the Indian space programme, rather than just matters related to the espionage case and his 1994 arrest. For the script, he also took inspiration from Narayanan's autobiography Ormakalude Bhramanapadham (2017) and Arun Ram's official biography of the scientist titled Ready To Fire: How India and I Survived the ISRO Spy Case (2018).

In October 2017, Madhavan confirmed that pre-production work for the film was underway and that he would portray Narayanan from the ages of 27 to 75, and that he was gaining weight to film the scenes featuring the older version of Narayanan first, after taking advice from Aamir Khan. Madhavan also announced that alongside his screenwriting and acting credits, he would also be one of the producers of the project. +more In regard to the making of the film, Madhavan stated that he hoped to differ in the script in comparison to other biographical films, and suggested that he would not call the film a "biopic" but an "incisive investigation into a brilliant mind and India's ambitious space technology". He also added that he felt that Madhavan was the "only Indian actor qualified to do this part" owing to his background as an electronic engineer with air-force training, and because he was "a thinking-actor who is also well-read". Madhavan was later announced as a joint director of the film.


Principal photography began on 4 January 2019 in Mumbai and was shot as a multilingual, with scenes simultaneously filmed in the Hindi, Tamil, and English languages. A few days after the start of the shoot, Mahadevan left the project owing to prior commitments and Madhavan took over as the project's sole director. +more Film director and writer Prajesh Sen, who had previously co-written Ormakalude Bhramanapadham and worked on a documentary titled Nambi The Scientist, joined the project as a co-director. Sukhmani Sadana worked on the film as an additional screenplay and dialogues writer. Scenes featuring Madhavan as the aged Narayanan were filmed first, with the actor taking up to 14 hours to get into the look following extensive make-up. During the first schedule in India, Simran joined the film's cast to portray the wife of the lead character, while actors Shah Rukh Khan and Suriya agreed to make cameo appearances in the Hindi and Tamil versions respectively as themselves. Both of the actors did not charge a fee for their participation in the film. Other actors who joined the cast during the production were Tamil actor Jagan to portray a scientist, Rajit Kapur to feature as Indian physicist Vikram Sarabhai in the Hindi and English versions and Ravi Raghavendra as Vikram Sarabhai in the Tamil version.

In late January 2019, the team moved to film scenes in Georgia and Russia. The team completed the shoot five days prior to the schedule, despite shooting in unfavourable weather conditions. +more In April and May 2019, the team shot scenes in India, with Madhavan shaving his beard to play a younger version of the character. The team subsequently moved on to film the final schedule in France and Serbia. Production was completed in Serbia during June 2019, with Scottish actors Ron Donachie and Phyllis Logan also a part of the final schedule. The shoot of the film took 44 days to complete. Post-production began in July 2019, with music composer Sam C. S. completing the background score by mid-October 2019. In August 2020, Madhavan revealed that the film had reached the final stages of post-production work and that only fifteen days of work were remaining to complete final sound mixing, mastering and digital intermediate tasks.

A launch event also coincided with the teaser release, with Nambi Narayanan himself in attendance. +more A theatrical trailer of the film was released online on 1 April 2021. Madhavan recalled a conversation that he had with Narayanan to explain the trailer's release coinciding with April Fools' Day, where the scientist had described himself as a "fool" who had been the "victim of his own patriotism". Madhavan stated he hoped to dedicate the trailer to these 'fools' who are "incredible unsung heroes and make this world a better place".

The trailer received positive responses, with Manoj Kumar of The Indian Express and a reviewer from The News Minute both calling the trailer "riveting". Madhavan and Narayanan met with India's Prime Minister Narendra Modi to show him clips from the film. +more Modi later tweeted that the "film covers an important topic, which more people must know about" and praised the footage that he was shown. A number of film personalities including Amitabh Bachchan, Priyanka Chopra, Suriya, Hrithik Roshan and Samantha Ruth Prabhu also shared and praised the trailer.
