No Dale/Erebor prologue. This was cut because the dwarves’ backstory is told in a much better fashion when they are in Bag End.
Bilbo’s opening lines remain, but Frodo is removed
Some dwarf silliness is gone from the Bag End sequence (just a few shots)
No Necromancer/Dol Guldur subplot. It distracts from the main quest and was poorly conceived and executed anyways. As it was in the book, it is only briefly hinted at now.
No Radagast whatsoever
Azanulbizar flashback is gone, although I MAY reinsert it depending on how the third film edits into the picture. It gives background on Thorin and Azog (who I will get to below)
Azog. This is one of the biggest issues with the fanedit. Azog is a lousy CGI villain that looked immediately dated upon the film’s release. However, Jackson made him the primary antagonist across the three films and his role is unfortunately essential. Even so, I have cut his role down considerably in AUJ.
Troll scene has been trimmed, with some silliness removed
The Daylight orc chase is gone. I spliced the company checking out the troll cave with their entrance to Rivendell.
No White Council/Galadriel/Saruman
The Stone Giants, while they were in the book, were overdone and ridiculous in Jackson’s film. They have been cut.
All scenes with Gollum are untouched!
Goblintown escape has been cut drastically, removing almost all of the physics-defying stunts and cartoonish CGI bits.
The tree fight/eagle rescue sequence is gone. This is another book scene I had to cut due to Jackson’s mishandling. It was obviously beefed up late in production in order to have a more “action-packed” climax for AUJ.
The film ends with Bilbo meeting back up with the dwarves outside Goblintown, and he still gives his nice little speech. Orcs suddenly show up and the party begins to run…however the beginning of the chase segues immediately into the beginning of DOS, where they are being chased into Beorn’s house.
