Gut feeling: INFJ, INFP, INTP, ENFJ
So that makes my possible orders of dominant functions look like this:
IN, EF, IT
IF, EN, IS
IT, EN, IS
EF, IN, ES
A few Edward Norton basics and influences:
-B.A. in History from Yale.
-Mother was an English teacher
-Father is an environmental lawyer.
-Worked for his Grandfathers affordable housing company in Japan.
-He worked as a waiter, a proofreader, and a director's assistant to try to get his foot in the door in New York City while pursuing acting.
-Hates finance.
-Hates selfishness.
My take on all of that is that Ed's an active humitarian and fluent at writing about world issues and looking into history to understand world issues. (extremely INFJ)
If anything Edward Norton is at the MARGIN because of how well adjusted he is from his vast life experience. Lots of inferior traits that can be picked out as seemingly dominant, so that's the first hindrance to labelling him with a type. Also, I hope you guys aren't trying to type him by watching his movies because he's a brilliant actor who can portray many roles with differing types. Watch his interviews and several things, I think, leap from the page.
If you guys could watch part 3/7 on youtubes Actors Studio with Edward Norton, Edward goes into detail about his method and being a representation of the character. He really likes to break things down, and dissect things, which is an awful lot like any INFP, INTP, and INFJ. It's the way in which he gives the information though that stands out. He doesn't speak with the facts only, like an INTP (sorry guys, no insult intended). He doesn't work just in theories, he discusses his method by how he relates to it, how he feels about it which is more of an EF trait. However, I think he might be an INFJ who was raised by an INTP mother who taught him to push his tertiary TI button, and if at the margin with a weak IN, weak EF, and weak IT, in that order, the case for an INFJ makes a lot of sense.
He'd love to be a pilot, and hates finance and he hates selfishness (all very un ISTJ like). He talked about having to get out of his own head, unlike some actors who live there naturally and are the same off the screen as they are on the screen, whereas, Edward has to force himself to move out of his headspace, like what is said about INTP's, INFJ's and INFP's.
There is no way he's an ISTJ, say what? Dominant IS, with ET, IF. He'd be a terrible actor, unable to tune into the thoughts and emotions of his characters. His struggle with acting does not seem like an S struggle at all in any way shape or form. As well, ISTJ's are naturally disposed to doing all things finance, and would probably find writing screenplays and movies, and studying history to be less than practical or necessary. As well, look at the plenthora of easily identifiable ISTJ actors on this list:

Maybe even INTJ with IN, ET, IF. He definitely has a strong introverted intuition and is like the writers of other counterpart INTJ's. Again, he's sooo at the margin that I can hardly make up my mind what traits he pulls from amongst the ones we've all discussed.
