In Empire's recent video interviews with the cast of The Hobbit: An Unexpected Journey, Peter Jackson revealed a couple of interesting titbits about his intentionally mysterious cameo in the film.
If you haven't seen it already, it's probably best if you don't know – but if you have seen the first Hobbit movie already, here's where he was hiding: in Erebor, dressed up as a dwarf, high-tailing it away from Smaug as the wicked wyrm blasted his particular brand of firey halitosis all upside The Lonely Mountain.
But as most dwarves in the film are bearded, helmeted and armoured, it's very difficult to make him out without knowing where he'll be in advance.
The question is then why he chose that role – why did Peter "Carrot Chomper" Jackson hide himself away from the limelight this time around?
"I didn't have a great deal of choice," he explains. "There weren't any human characters in this film, and there weren't any hobbit roles I could play... and I'm not an elf."
What he goes onto add we've leave you to find out for yourself in the video above, and if you want to find out more from our full-length interview with Peter, you can do so here. Plus, for info on what deleted scenes you can look forward to on the extended edition DVD and Blu-ray, click this way...
