From The Telegraph:
If many a blockbuster is born of books, many a book-sale boom is borne by blockbusters. Harry Potter and The Goblet of Fire may have not set the city box-office on fire, but it sure has sparked a fresh sales spurt in the J.K. Rowling series. And sales of author Arthur Golden’s Memoirs of a Geisha have picked up “dramatically” in anticipation of director Rob Marshall’s December release, starring Michelle Yeoh and Zhang Ziyi.
“The movie-book relationship is getting bigger and better. Every time a film releases, the original novel gets a fresh impetus,” says Sidharth Pansari of Crossword. “A Lord of the Rings and a Harry Potter invariably sell more when the movie hits the theatres.”
Sometimes the impact is not that direct. Mario Puzo’s Godfather sold big when Sarkar did well at the box-office. Helen Keller’s autobiography The Story of My Life was in “huge demand” when Sanjay Leela Bhansali’s Black hit multiplexes.
Comics, too, benefit from big-screen blitzkrieg. “Spiderman and Batman comics sell more when their movie versions are in town,” says Gautam Jatia of Landmark. “Pokemon Annual became a big draw when Pokemon was shown on TV.”
