I agree with '3:10 to Yuma'. I think it is nearly great, and I do like Ben Foster.Great list. I will add:
The Big Country (1958): maybe not an all-time great, but a classic, big-screen epic.
3:10 to Yuma (2007): not an all-time great, but Ben Foster (also in Hell or High Water) is such a great villain.
Back on topic: Ruthless People has some great quotes. The scene with Ken Kessler (Judge Reinhold) trying to sell a stereo system to a teenage couple is funny:
Ken Kessler : Check it out, my man! This is the Dominator X-10. Thirty inches of thigh-slapping, blood-pumping, nuclear brain damage!
Heavy Metal Kid : Bitchin'! Hey, what's it fucking cost?
Ken Kessler : That's the bitchin' part about it! It don't matter! If you can't afford it, FUCKING FINANCE IT!
[turns it on]
Ken Kessler : So what if it's as big as a Subaru and costs as much? You'll never have to trade this in! This is gonna be with you for the rest of your life! And when you die, they can BURY you in it!
I love Westerns, but I have a hard time watching pre-1960's movies. The acting and pacing are just too different for me.
Some of my favorite crime/mafia movies:
-'Miller's Crossing'..."Nothing more foolish than a man chasin' his hat. "
-'Once Upon a Time in America'...No quote for this one, the music and the camera are as important as the characters.
-'On the Waterfront'..."It wasn't him, Charley, it was you. ..."
-'Cool Hand Luke'..."Sometimes nuthin' is a pretty cool hand."
