I greatly enjoyed watching The Avengers, even though I've never read any of the comics. However, Nick Fury to me didn't seem to be so much of a comic book character as he was just good ol' Samuel L. Jackson.
A prime example of what I'm talking about is this exchange. (Summarized from vague memory. If anyone's got a transcript or something, please edit for accuracy.)
FURY: Turn this thing south! We need to get away from the city if we're going down!
HELMSMAN: But, sir! The navigation computers are down!
FURY: Is the sun rising in the east?
HELMSMAN: Beg your pardon, sir?
FURY: I said, is the sun rising in the east?!
HELMSMAN: Uh, yes sir!
FURY: Then put it on your left!!
Is this because Samuel L. Jackson is just that good of a fit for the character? Or was there really not that much of the real Nick Fury on the screen?
