I watched war films so that I have an understanding of what has already been done and what I could do in 'Paltan.' I watched films like 'Atonement,' 'Schindler's List,' 'Inglourious Basterds,' 'The Reader,' 'Downfall,' 'Saving Private Ryan,' 'Katyn,' 'Enemy at the Gates' and many more. I hope it all reflects in my performance in the film.
