'The Ghazi Attack' has been intriguing the audience with its thrilling trailer about an important event in Indian history: a war we did not know about!

Rana Daggubati, who will be seen playing a Lieutenant Commander Arjun Varma in 'The Ghazi Attack', has written a letter to the president of India.

During the course of working on the film Rana met some real navy officers who were on board.

The actor was extremely moved on hearing about their challenging experience, and decided to write a letter to the president for acknowledging the Indian armed forces, as they are the unsung heroes whose immense contribution the nation must know about.

Rana Daggubati says, "Post Ghazi, civilian like me have understood a lot about victorious battles that have been fought by all our armed forces on the borders so as to keep us safe. As a civilian I did not know about these victorious tales and like me there are many others who did not know much about it, to us it's a letter to acknowledge these heroes and make sure we know more about these unsung heroes and their tales of victory."

The upcoming movie rekindles the mystery of what happened on the night of December 3 and what exactly caused sinking of the PNS Ghazi attack from the Indian Navy.

Movie is a tribute to the immense contribution of the navy officers and the movie screenings across India is a salute to the brave-hearts who fought valiantly for our nation. The Ghazi Attack stars Rana Daggubati, Atul Kulkarni, Kay Kay Menon, Taapsee Pannu and late veteran actor Om Puri and the audience is expecting stellar performances.

Karan Johar & AA Films Present, India's first War-At-Sea film, 'The Ghazi Attack' is slated to release on February 17, 2017.

The film is inspired from true events, a classified mission conducted by the Indian Navy against their Pakistani counterpart in 1971 that not many people know about.
