Veteran film-maker JP Dutta believes in making his projects look authentic, and his upcoming war drama, Paltan, is proof of that. The lead characters are all based on real-life soldiers who fought in 1967. Arjun Rampal plays the role of Col. Rai Singh, who was commanding a unit at the border outpost at Nathu La when the Chinese attacked.

Gurmeet Choudhary plays Captain Prithvi Singh Dagar who was detailed as the Officer in charge of a party ordered to strengthen the wire laying party opposite South shoulder at Nathula.
