2. Dwarf Women
Its a blink-and-youll-miss-it moment, but when we are introduced to Dale in Bilbos introduction (pre-Smaug attack), we see a couple of dwarf women with some mighty fine facial hair. Its not quite the flowing beards of Gimili or Thorin, but its certainly some impressive sideburns that would make them the envy of most modern men. This is obviously a throwback to The Two Towers, when Gimili is explaining how dwarves of both genders look similar, Aragorn makes a joke it is down to the women's beards. It may not be full beards (thatd probably confuse newcomers to series), but its a nice nod that Jackson still remembers the smaller parts of his trilogy.
