Now this is precious. $6.2 billion and counting. That's how much films based on J. R. R. Tolkien's books have made in all at the box office so far. And there's still one part of The Hobbit trilogy to come. The Lord Of The Rings (LOTR) and The Hobbit are also on the list of Top 10 best selling books of all time - LOTR at No. 2 with 150 million copies sold. The Hobbit is No. 6 with 100 million copies sold.
