GD has written a book about Tamil cinema titled "The Best of Tamil Cinema: 1931 to 2010", in English, which was released by Legendary Actor Kamal Haasan on 2 March 2011 in the presence of eminent film makers. Super Star Rajinikanth personally appreciated the book by giving a memento for the fantastic research and writing on Tamil cinema. The book has reached out to many universities worldwide and has become a reference point on Tamil cinema for many interested foreigners to know about Tamil cinema.
