Speaking about the home work he had to do for the role, the 34-year-old actor said, "It was quite easy because Ashutosh had done two years of research on the Chittagong uprising, Surya Sen and all the other characters that were part of the uprising. There's actually very little photographic documentation of Surya Sen. There are a very few photographs after he was arrested. The entire incident isn't very extensively documented."
He further added, "Compared to Bhagat Singh and Chandrashekhar Azad, not much is written about Surya Sen. But whatever Ashutosh could get his hands on and obviously relying on the book, 'Do and Die' we put together the character."
KHELEIN HUM JEE JAAN SEY also stars Deepika Padukone and is all set to release on December 3.
