Saw the movie a couple of days ago. I naturally had to make a thread about it. I'm still quite a novice in the art of typing, so bear with me (Get it? BEAR with me! BEAR = BEORN)
Bilbo - ESFJ (Ti for inquisitiveness, Ne for latent sense of adventure)
Gandalf - INTP (He's still grey, not white)
Thorin - ESTJ (Si is glaringly obvious, I can't imagine an ENTJ being consumed by his past)
Balin - ISFP (Basketball)
Beorn - ISFJ (ISTJ in the book)
Legolas - ESFP (Se to the core, uses a lot of Te in the movie)
Tauriel - INFP
Bard - ISTJ
Radagast - ISFP
Thranduil - ISTP?
Smaug - xNTP?
Sauron - ENTJ (Bad stereotype, but I want him to be relevant to this thread)
