If you've seen The Hobbit, you know that the main goal of the Dwarf company in the movie is to regain the gold that the dragon Smaug stole from them. In the first few minutes of the movie, you can see the amazingly large collection of gold coins, weapons and jewelry that Thorin and company want to regain. This treasure hoard wasn't all digital, and it seems that it was so grand, that the producers of the movie used up all the gold paint that was available in New Zealand. They used up so much, that they had to pick up more from Germany!
Another fun fact about the Hobbit is that all props and makeup had to be intentionally redder than normal. This is because when filming everything at 48 frames per second (as opposed to 24), the cameras pick up a lot more yellow color, and making things redder offsets this effect.
