The yet-to-be-titled film is being produced by Dinesh Vijan, who has bankrolled movies like 'Stree', 'Hindi Medium', 'Cocktail' and 'Bala' to name a few.
The upcoming film is a biopic on Second Lieutenant Arun Khetarpal, who was an officer of the Indian Army and a posthumous recipient of the Param Vir Chakra, India's highest military decoration for valour in face of the enemy. At the age of 21, he sacrificed his life during the Indo-Pakistan War of 1971.
Reportedly, the film will pay a tribute to him and also will focus on his relationship with his father.
Sriram gave a groundbreaking role to Varun with 'Badlapur'. With the film, the 32-year-old actor delivered his career's best performance, leaving people surprised with his raw and rugged character.
Apart from the forthcoming biopic, Varun will be next seen in 'Coolie No. 1' and 'Street Dancer'.
