Robert Mitchum doing one of the best opening monologues ever (Criterion trailer for The Friends of Eddie Coyle)
According to Wikipedia, these are the characteristics of the anti-hero as identified by critics:
The death of Eddie Coyle could hardly be more fitting for an anti-hero; passed out after drinking too much at a hockey game, he is shot in the head by the snitch that betrayed him to both the mob and the cops. Robert Mitchum plays the anti-hero Eddie “Knuckles” Coyle, a mid-level gunrunner who’s trying to keep his dependable Irish wife and their three kids off welfare and himself out of prison. So while still supplying guns to a group of high-profile bank robbers he’s also working for Uncle, hoping that he can get a phone call made to the judge who is about to sentence him for an earlier conviction. Part of what makes Coyle such a compelling anti-hero is, despite his less honorable characteristics, that he demands your respect. He’s past his prime, but still handsome. He’s selling out his friends to the government, but only because he needs to take care of his family. He’s never attained much notoriety in criminal circles, but not for lack of intelligence or toughness of character. Scheme as he might, he’s helpless in a world over which he has no control.
