What is it about dragons that captures our imagination so? Is it their massive size, their impressive wingspan, their ability to breathe fire — or maybe all of the above? Their serpentine visage has graced the landscape of cinema, even entering into the realm of television; but before there was Drogon, Draco or even King Ghidorah, there was Smaug. You could say that he's the grandfather of all dragons; so, given the pivotal role he plays in J.R.R. Tolkien's The Hobbit, it's befitting that the title of the second instalment of director Peter Jackson's Hobbit trilogy bears his name.
