For Chakravyuh, the actor plays a police officer investigating communist guerillas in the Indian countryside.
He told The Times of India: "I was not much aware about the issue and this is the reason why I feel that this film is important for the youth. They need to know where exactly does the heartland of India lie and what exactly is transpiring there.
"It is going to open many eyes because the film explores the situation that our country is in.
"The film is full of complicated characters and the part which I am playing is one of the toughest that I have played in a very long time.
"There is so much happening to this character, right from the dilemma that he goes through to the pain of betrayed friendship to a conflict like the situation happening at home with his wife, who is also a cop."
Rampal added: "All credit to director Prakash Jha that he has made all his characters well layered and also very justified in what they do. The reason why everything... on screen carries meaning and purpose is because Prakash comes with a lot of clarity."
Jha recently said that he shared a special bond with Rampal, who he has worked with since 2010's Rajneeti.
