I think perhaps Narzug is an orc captain involved in the attack on the barrels/Wood Elves in film 2. When it was two films that would have placed him in the first movie hence the early release. I think we may have seen him a couple of times, I think he's the orc in the trailer that jumps towards Thorin in the barrel and also the one who is being interrogated by the elves (he says 'the dwarf will never be King' in the new trailer). I could be wrong about that but the appearance fits.
As for the Extended Edition I'd say it's well worth it. I haven't actually watched the Extended cut yet (got that planned for Thursday evening!) but like you my main interest is all the behind the scenes stuff as I absolutely adored that on the LOTR DVDS which are still to my mind the greatest DVD extras ever produced.
As for the Production Blogs I'm happy to report that none of them are on there (they were all released on the theatrical cut DVD) and there is hardly any overlap between them and the new documentaries - it's basically all new stuff. It's hard to quantify exactly but I reckon there's about 8 hours of new behind the scenes documentaries on there - it's reeeeeally good stuff.
Most of it is about the production so every major scene (think Bag End, Rivendell, Radagast White Council, Trolls etc. gets its own 10-15 minute documentary covering the filming.
There's then another set that looks at the design, planning and casting of the movie, a 15 min feature on Bilbo, hour long feature on the dwarves, 15 mins each on the trolls, Azog, radgast and the goblins and another one about building the sets that I haven't got too yet. It's all absolutely awesome and very much in the style of the LOTR ones.
There's also one commentary that I haven't watched yet. That would be one small complaint I had - the LOTR movies had 4 commentaries compared to this one, it's a shame that the cast and the pre/post production teams don't get a chance to shine.
The other minor complaint is that the vast majority focuses on the 'production' process, some of my favourite docs on the LOTR DVDs were the 'Book to Film' 'Editing' 'Sound Design' and 'Visual Effects' docs. These don't have dedicated docs on AUJ but are interwoven at parts into the other docs.
However, overall they're excellent and I'm basically complaining that the second best DVD extras of all time aren't quite as good as the best DVD extras of all time! I would heartily recommend picking it up. It's only £14 on iTunes too! (although you don't get the commentary and you'll need about 23GB on your PC!
