Rocketry: The Nambi Effect which released on July 1, 2022 is actor Madhavan's maiden directorial venture. The movie is a biopic on ISRO scientist Nambi Narayanan who was falsely accused of espionage in 1994. Nambi Naryanan belongs to a Tamil Brahmin family from Nagercoil and be it in behind-the-scenes or in the promotions of the film, it was made clear that Nambi Narayanan's religion was as much a part of his life as science. 

While this may not be a cultural stick out for an average South Indian [Nagercoil is a city in Tamil Nadu, the Southern most state of India], some Rocketry reviews from other parts of the country seem to have questioned the display of Nambi's spirituality onscreen [Understandably so, given the looming Hindu-fervour there].

This is being #Hinduphobic
Why does it trouble U if Narayanan is a Hindu patriot and prays during crucial times?

Madhavan, however has called out the author of the review on Twitter implying, this angle has nothing to do with the movie, and being a biopic it is simply showcasing Nambi Narayanan's true personality on screen. In a now-deleted quote of the tweet above, Madhavan wrote, "We thought it was in terrible taste too.. this is who Nambi sir is .. I am totally okay if you did not like or hated the film and I will take it in the chin..but why this ??Come on -we are way Better than this.Regretful"
