Douglas Anderson, a Tolkien scholar, recently reported seeing one of his books on a shelf in a TV series. The eminent critic Michael Dirda replied: 

More likely the books were bought en masse, without regard for titles and attention paid largely to their color and general look on the shelf. My friend Chuck Roberts, owner of Wonder Book and Video, has a strong business in selling books by the foot for movie and theatrical sets. — Still, sometimes thought does go into these background bookshelves. I remember Chuck once asking me to recommend titles for Hannibal Lecter’s library. 

This comment prompts an excellent thought experiment: What would go on Hannibal Lecter’s shelves? One might extend this to other fictional figures, which might seem like a vast field of inquiry except that many fictional movie characters obviously don’t read books at all. Tony Stark, for instance, reads only technical manuals and tweets. So: which famous movie characters read? And what do they read?
