Guillermo Del Toro heeft een exclusief interview gegeven aan de website totalfilm.com, waarin hij enkele interessante details vrijgegeven heeft over The Hobbit:
The way I phrased it to Weta, I said we would keep the DNA in the same gene pool as the Rings trilogy, but that we would generate a different type of character. For example, in the trilogy most of the creatures are brutish or inarticulate.
In The Hobbit, the creatures speak: Smaug has beautiful lines of dialogue; the Great Goblin has beautiful lines of dialogue; many creatures do. So we had to design them with a different approach because you are not just designing things that are scary.
I also wanted some of the monsters in The Hobbit to be majestic.
I wanted the Wargs to have a certain beauty so that you don't have a massively clear definition: what is beautiful is good and what is ugly is not. Some of the monsters are absolutely gorgeous.
I think one of the designs I’m the proudest of is Smaug. Obviously he took the longest. It’s actually still active: we’re finishing his colour palette and a little bit of the texture. But the bulk of the design took about a year, solid. It’s because of the unique features of the dragon.
Early in production I came up with a very strong idea that would separate Smaug from every other dragon ever made. The problem was implementing that idea. But I think we’ve nailed it.
