The film, which deals with the subject of euthanasia, has been selected to be a part of the permanent script collection of the Library Academy of Motion Picture Arts and Sciences.
The Krrish actor commented on the film: "What I would say is that it is some kind of wonderful. You will have a smile on your face and a tear in your eye. It is timeless."
The Hindi film star was also recently nominated for 'Best Actor' at last month's Filmfare Awards.
The project reunited Roshan with Dhoom 2 and Jodhaa Akbar co-star Aishwarya Rai.
