Even though the character of Galadriel doesn't make an appearance in JRR Tolkien's The Hobbit, Cate Blanchett was so perfect portraying the grandest elf of all that it was a given she'd be back.
Along with Blanchett, even more supporting cast was announced. I dont recognize most of these folks by name, and since they're mostly playing dwarves I probably won't recognize them on screen either!
Ken Stott (Charlie Wilson’s War) is the Dwarf Lord Balin
Sylvester McCoy (Doctor Who) is the wizard Radagast the Brown
Mikael Persbrandt (Day and Night) is Beorn, an enormous shape-shifter who can take the form of a bear
Ryan Gage (Outlaw) is Drogo Baggins
Jed Brophy (The Lord of the Rings) is the dwarf Nori
William Kircher is the dwarf Bifur
