How 'bout Logan's Run, Cube, Clerks/Mallrats/Dogma/Jay and Silent Bob, Reservoir Dogs, Blue Velvet, Trainspotting, Excalibre, or any of at least half a dozen Jacky Chan movies including Police Story I & II, Project A I & II, Dragon's Forever?
While I'm at it, I have to nominate The Killer, A Better Tomorrow, and Bullet in the Head as John Woo at his best and Hard Boiled for more in the Chow Yun-Fat oeuvre. Maybe very successful/mainstream in Hong Kong, but definitely cult status in the West.
I'd also like to mention Pulp Fiction, Kill Bill, The Usual Suspects and Fight Club, but I'm not sure that they qualify as cult movies.
Oh! I almost forgot The Boondock Saints. Sensational!!!
[Fire alarm goes off, all three cock their weapons, II Duce jumps behind Yakavetta and puts his shotgun to his head. Conner and Murphy jump onto tables]
Connor: Now you will receive us.
Murphy: We do not ask for your poor, or your hungry.
Connor: We do not want your tired and sick.
Murphy: It is your corrupt we claim.
Connor: It is your evil that will be sought by us.
Murphy: With every breath we shall hunt them down.
Connor: Each day, we will spill their blood till it rains down from the skies.
Murphy: Do not kill, do not rape, do not steal, these are principles that every man of every faith can embrace.
Connor: These are not polite suggestions, these are codes of behavior and those of you that ignore them will pay the dearest cost.
Murphy: There are varying degrees of evil, we urge you lesser forms of filth not to push the bounds and cross over, into true corruption, into our domain.
Connor: For if you do, one day you will look behind you and you will see we three. And on that day, you will reap it.
Murphy: And we will send you to whatever god you wish.
[Murphy and Conner join II Duce behind Yakavetta]
Connor, Murphy, Il Duce: And shepherds we shall be, For thee my lord for thee. Power has descended forth from thy hand, that our feet may swiftly carry out thy commands. So we shall flow a river forth to thee, and teeming with souls shall it ever be.
Il Duce: In nomine Patri
Connor: Et Fili
Murphy: Spiritus Sancti
[they execute Yakavetta]
[after Rocco accidently kills his girlfriend's cat]
Connor: Donna's gonna be angry about her cat.
Rocco: F**k, she's on every drug known to man. She'd have sold the thing for a dime-bag. Screw her.
[laughs]
Rocco: I do kinda feel like an a$$hole, though.
Connor: Yeah, Roc, you sound real remorseful there.
Rocco: I killed your cat, you druggie b!tch.
Donna: What? Why?
Rocco: I thought it would bring closure to our relationship.
Donna: You killed my... my...
Rocco: [putting a gun to his head] Your what? I'll shoot myself in the head if you can tell me that f**king cat's name! Your what? Your precious, little...
Donna: Skippy! Skippy!
Rocco: Aw, Jesus! What color was it, b!tch?
Connor: We haven't really got a system of deciding who, Roc. It's just...
Rocco: Me! *Me*! I'm the guy! I know everyone! Their habits, who they hang out with, who they talk to! I've got phone numbers, addresses! I know who they're f**king! I know where they *live*! We could kill *everyone.*
Murphy: So what do you think?
Connor: I'm strangely comfortable with it.
Rocco: Anybody *you* think is evil?
Connor: Aye.
Rocco: Don't you think that's a little weird, a little psycho?
Connor: You know what I think is psycho, Roc? It's decent men with loving families. They come home every day after work and they turn on the news. You know what they see? They see rapists, and murderers and child molesters. They're all getting out of prison.
Murphy: Mafiosos. Getting caught with twenty kilos. Getting out on bail the same f**king day.
Connor: And everywhere, everyone thinks the same thing: that someone should just go kill those motherf**kers.
Murphy: Kill 'em all. Admit it. Even you've thought about it.
Rocco: You guys should be in every major city. This is some heavy s#!t. This is, like, Lone Ranger heavy, man.
Rocco: Shut your fat a$$, Rayvie! I can't buy a pack of smokes without runnin' into nine guys you've f**ked!
