Given her curly hair and her role as a Tamil-speaking instructor in the malayalam film Premam, Sai Pallavi, who plays Major Mukund's love interest, appears to have been chosen for the part. Although her character is portrayed studying media and is addressed in English, there is a scene in this movie where she speaks to her professor in Malayalam. This decision seems inconsistent, particularly when she is the only one using her mother tongue in situations where other people are using English, which creates a strange dissonance. It would have seemed more genuine if a Malayali had dubbed Sai Pallavi's malayalam dialogues instead of her.

Another area where Amaran falters is in how Mukund's family is portrayed. Why the director chose not to depict Major Mukund's family as an Iyengar household is still unknown. His father is portrayed in the movie as a quiet character, almost as a background prop, overshadowed by a strict mother who often expresses her disapproval of his job decision and declines to participate in important events like his pipping ceremony at the passing out procession. Throughout the movie, Sivakarthikeyan is also heard referring to his father as "Naina," which appears to be intentional.
 
Why does the distributor, red Giant, which is controlled by the DMK first family, and the director, and producer, Kamal Hassan, a part-time politician, find it problematic to portray a hero as coming from the community he hails from? Is the filmmaker adhering to the Dravidianist myth that "Brahmins in tamil Nadu do not join the Army"?
Because they are all our protectors and without them, we would not be secure for a single moment, we appreciate troops for who they are, regardless of their caste, creed, religion, or anything else. However, it begs the question of why Major Mukund does not receive the same level of attention while Indhu Rebecca, his widow, is highlighted as a Christian in nearly every scene. In actuality, Indhu is scarcely seen wearing the crucifix around her neck in the images that are accessible online.
 
She is also depicted as being very devout, though it's unclear how much of that is accurate. If all these details had been noted, the same effort could have been made for Major Mukund's character as well; he only displays his "ishta deivata" in one scene, which is Swami Ayyappan.
If such significant information are purposefully omitted, it cannot be said to as a biopic. Films like Soorarai Potru, which is said to be a biography of Captain Gopinath, a tamil Brahmin, but portrays him as a member of a foreign group and an adherent of anti-Hindu bigotry EV Ramasamy Naicker, are examples of this misrepresentation.
