Peter Jackson has spent years making JRR Tolkien's Middle Earth into a CGI spectacular - and the director has revealed that he intends to end things with a bang.
The final instalment in The Hobbit trilogy, entitled The Battle of the Five Armies, is set to culminate in an epic, 45-minute battle scene.
Oscar-winner Jackson, who also directed The Lord of the Rings trilogy, told Entertainment Weekly that designing and creating the footage was a feat in itself.
"There's a lot of logistics that have to be thought through," he said.
