Malhotra, who essayed Captain Batra's role in a recent biopic, penned an emotional note on the war hero's birth anniversary.
The actress, who is often surrounded by controversies, hit the headlines in 2017 when she called filmmaker Karan Johar 'intolerant' towards outsiders.
Sidharth Malhotra's meeting with Vishal Batra, Captain Vikram Batra’s brother, gave him the vision to create the character.
Showcasing various clips of his training on Instagram, Sidharth also acknowledged that out of all his films, it is 'Shershaah' in which he has spent the maximum amount of time for prepping.
The movie features actor Sidharth Malhotra as Captain Batra, who was martyred while fighting for the country during the 1999 Kargil War with the Pakistan Army at the age of 24.
Also starring Kiara Advani, 'Shershaah' is headed for a direct-to-digital release on Amazon Prime Video on August 12, given the coronavirus pandemic.
Captain Vikram Batra continues to motivate the present generation of officers and would do so in perpetuity.
