So, who are some of the notable characters that were in the movie but not produced?
Nori, Dori, Ori, Bifur, Bofur, Bombur, Oin, Gloin, and the Dwarf King from the prologue
Thranduil (on his Elk?), Galadriel, Elrond, Thranduil's troops
Azog, basic carded Orc
WIZARDS / SORCERORS
Saruman, Radagast, Angmar, Necromancer
I also think the Eagles and the three Trolls would be good additions as well.
