The lead performer trained to handle a real, operational assault rifle together with his fellow cast members, and he said the experience was physically taxing. The film was also shot on location, including at the actual sites where Major Mukund Varadarajan had been billeted while serving with his regiment.
Sai Pallavi's visit to the National War Memorial ahead of the film's release sparked controversy after an interview she gave in January 2022 resurfaced online, in which she said people in Pakistan regarded the Indian army as a terrorist organisation in much the same way some in India regarded Pakistan. She referred to the violent incidents depicted in The Kashmir Files (2022) and cited an example of a Muslim driver transporting cattle who was allegedly lynched by a mob chanting "Jai Shri Ram." The remarks provoked widespread online backlash, with the hashtag #BoycottSaiPallavi trending.
