The Stranger (High Plains Drifter)
Being dead to start with, you couldn't really say that Eastwood's stranger was exactly courageous. He was more like an agent of God- the Old Testament YHWH version- carefully and methodically forcing the people of the town to see into their own souls in such manner as they could not deny.

Raymond Shaw (The Manchurian Candidate)
From Sinatra's final voiceover: "Made to commit acts too unspeakable to be cited here... by an enemy who had captured his mind and his soul... he freed himself at last... and, in the end, heroically and unhesitatingly gave his life to save his country."

Ed Exley (LA Confidential)
Exley showed great exceptional integrity to truth in tearing down his apparently perfect career making achievement in the Night Owl Cafe murders.

Sarah Connor (Terminator 2)
She was the fiercest protective mother cub in the history of film.

Marge Gunderson (Fargo)
Fighting through the extreme cold and the discomfort and indignities of a late term of pregnancy, Marge quietly plodded forward to solve murders and -in the most understated way- provide a human soul and an understanding spiritual presence amidst all the greedy losers whose petty venality created so much suffering.

John Coffey (The Green Mile)
The coolest "magical negro" in movie history, and a striking figure. For being so nice though, note that he absolutely destroyed one jackass guard, and quite consciously pushed him into killing another inmate.

Robin Hood (The Adventures of Robin Hood)
Errol Flynn's classic 1938 swashbuckling Robin Hood can't be denied. His heroism did not have the flavor of self-sacrifice, but of proper pride and joy.
Maid Marion: You speak treason!
Sir Robin of Locksley: Yes, fluently.

Clarice Starling (Silence of the Lambs)
Her most impressive displays of courage came in her talks with Hannibal, knowingly making herself vulnerable to him in order to save the senator's daughter.

Ichabod Crane (Sleepy Hollow)
Notice how this version of Ichabod struggled constantly against his physical fears and sensitivities, trying to stoically choke it back again and again. Even more impressively, notice his integrity in following the empirical evidence where it led- even when it led to his beloved.
