Apparently The Hobbit Trilogy cost some serious Justin Bieber money to produce, even if it is expected to pull in multiple times its cost at the global box-office.

According to AP, the Peter Jackson helmed blockbusters cost a combined $745 million to make, a staggering amount of money that's nonetheless jarred firmly into a different context when you realise the 3 films will likely top $3 billion at the box-office.

The Hobbit: The Battle of Five Armies is due for release this side of Christmas, and is the final flick in the phenomenally successful Lord of the Rings series.

That's that, then.
