Sidharth Malhotra, on numerous occasions, has stated that the biopic on Captain Vikram Batra is his toughest project to date. In his bid to do justice to the Kargil martyr who was posthumously awarded the Param Vir Chakra, the actor met the hero's family, including twin brother Vishal Batra.

Talking to mid-day, Batra says that Malhotra is "the right guy" to tell the story of his brother's bravado. "While we had spoken on the phone a few times, I met Sidharth in Mumbai through Shabbir [Boxwalla, producer]. It was an emotional moment. Sidharth looks similar to Vikram, so we thought he was the right guy to play him. It was more of an introductory meeting." Interestingly, Malhotra will also play Vishal Batra in the outing that sees him in a double role.
