Everyone knows that the fantastical world created by J.R.R. Tolkien for The Lord of The Rings, The Hobbit and The Silmarillion is exceedingly vast and complex, filled with backstories and side adventures and its own mythic lore. Empire Magazine quizzed the Hobbit cast on their own knowledge of Tolkien Trivia. While most answers were pretty weak, Richard Armitage (Thorin) absolutely nailed it (looks like someone really researched his part). Could you?
