I was watching the new
Hobbit production diary 12 and found a interesting part of it. If you pause the video at 0:15 there seems to be a new orc (it shows the unfinished part of it). The orc appears to looks like Azog, but it isn't him as it does not have a missing arm. Also, on it's forehead there appears to be metal plates similar to those of Bolg. Is this a new orc, or is it a redesign of Bolg? Perhaps one of Bolg's bodyguards?
