Awww....such a great topic! Yes, Mr. Darcy has got to be INT, I'm leaning towards INTJ, & don't you think Elizabeth is ENFJ? They're so great! I just swoon watching that BBC version with Colin Firth.
Yes, and Anne with an "E" is an NF for sure, but Gil an NT? No, he's too outwardly gentle even when teasing her to be an NT. I think they're NF-NF. I do love seeing Anne soften her SJ Marilla, that brings me great joy as you see Marilla so clearly show her sentiment towards her--that Anne annoys her so much, but is lovable nonetheless.
Amelie is definitely an INF, but I think her match is SP or NF, with his childlike imagination & fun spirit.
Many of the interesting characters in I heart Huckabees were INs, but the other types/evil characters were caricatures of evil corporate life that it was a bit too self-conscious & pretentious for me. I don't like when the bad characters are displayed as caricatures, & the protagonists are fully developed. Annoying.
How about the characters in Lost in Translation? They seem NF/NT in their dreaminess & angst, trying to find meaning in life......
Maria in The Sound of Music is definitely an ENFP, she's called an angel, a demon, a pest (she can "outpester any pest"!), a girl when she fails as a nun. But Captain von Trapp I'm not sure, he could be an ISTJ or an INTJ, he's pretty rigid about his rules, seems SJ.
