Actor Varun Tej has shared insights into his character of an Air Force fighter pilot in the movie `Operation Valentine`, and said that roles like these are not easy, revealing about the homework he did to bring realism.

Reflecting on the challenges of portraying such a unique character, Varun remarked, "Roles like these are not easy, and it`s not like you are experienced or you see people from the Air Force in your day-to-day life. There was some homework that we did. We had a person from IAF who was working with us from the time the script was being made because we wanted to make a film that IAF is proud of also."
