Any long time Peter Jackson fans will know of his love for releasing extended versions of his Middle Earth movies - starting all the way back with the longer cut of The Fellowship of the Ring which was released in 2002. And is honestly the best version of the one of the finest fantasy movies ever made.
12 years on, he's still at it, delivering a longer and more in depth version of the Hobbit: the Desolation of Smaug. This new version comes on 5 disks and includes an extra 25 minutes of footage added to the running time, as well as more than nine hours of detailed extra features.
These docs are absolutely exhaustive and you can catch just a glimpse of the kind of access they had in this short clip, which deals with actress Evangeline Lilly and the work she had to do to become the elf Tauriel.
Lovers of extra features will want to get this massive box set right now! I still prefer the art for the DVD edition though, which is the second one below.
