Dwalin is the first dwarf to arrive at Bilbo’s home. Tolkien says he has “a blue beard tucked into a golden belt.” As you can see, Peter Jackson’s adaptation has done away with the multi-colored beard scheme, perhaps mindful that Tolkien wrote The Hobbit for children. Instead Dwalin’s most noticeable signifier is his bald, oblong head. Not a prominent figure in Tolkien’s books, Dwalin in the film is your stock-in-trade dwarf warrior, taciturn and Scottish-brogued (the more playful ones in the company conveniently have Irish or Northern Irish accents). In Tolkien’s books, we learn that Dwalin and his brother Balin fought alongside Thorin’s house at Azanulbizar; their father, Fundin, died there. So, yes, he’ll be killing lots of orcs.
