We already presented you with some fun trivia about the book-version of The Hobbit, but if you're interested in learning more about the behind the scenes actions involved with making the film version, io9 has you covered with all kinds of neat facts. For example:
Smaug Stole All Of New Zealand's Gold (Paint)
The greedy dragon's lust for gold could not be quenched even off the set. According to Scotsman The Hobbit crew used up all of the gold paint in New Zealand creating Smaug's lair. They used up so much paint that they actually had to pick more up from Germany.
That's a heck of a lot of gold paint!
