RAISING THIS OLD THREAD CAUSE I HAD AN EPIPHANY ABOUT GALADRIEL AND GANDALF'S TYPES AND WANTED SHARE IT IN AN AT LEAST RELEVANT THREAD, THOUGH THE MOVIE IS NO LONGER A HOT TOPIC.
Based on the movie, Gandalf is INFJ, check 0:40:
Galadriel, as you said, is ENFJ, check 0:38:
Saruman is ISTJ, check 0:47:
Bilbo feels more like a Fi type, probably an xSFP.
Frodo is INFJ and Sam is ISFJ.
Gimli feels like a feeler trying to act tough. ESFJ comes to mind.
Legolas, well the actor feels like ISFP.
Arwen, the actress feels like ISFP.
Eomer feels like ISTJ, he's too contained.
[MENTION=5356]Speed Gavroche[/MENTION], if you are still interested, about Derethor II, don't know but why did you assign INFJ to all the bad guys?
Anyway, I just wanted to put forward that Galadriel might be ENFJ and Gandalf might be INFJ and open that up to discussion.
Cheers.
