I saw "Kelly's Heroes" over 8 times in the theater alone. There was a $2 place not too far from school, and my friends and I would go over and watch the double features there a lot. "Kelly's Heroes" was the newer movie the first 3 or 4 times, but was knocked down to the second feature later on. I saw "Vanishing Point", and KH as a double feature at least twice.
Ones that always get me to watch:
The Godfather I and II.
Emperor of the North Pole.
The Getaway, perfect casting, except for (IMHO) the awful Ali McGraw.
Mr. Majestyk
Scarface.
Aliens
Terminator I and II
The 7 Ups.
Jaws 1
Predator
Star Trek 2, 4, and 6.
The Empire Strikes Back.
McQ, John Wayne isn't my favorite, but that Trans Am he drives is!
Kelly's Heroes, of course.
Die Hard 1 and 2
The Good, The Bad, and The Ugly.
Once Upon A Time In The West.
The Wild Bunch.
Animal House.
And I can't resist watching and goofing on "Dune" from 1984. I can't let it go, I have to watch it and it's so bad it amuses the hell out of me. The new one is much better, but like the book, it takes itself way too seriously. Another one I can't resist is "Heaven's Gate". I saw it opening day, what a stinker, but I have to watch it. A local station had it on in the middle of the night a couple of years ago. It wasn't listed on my channel guide, but there it was in all of it's underexposed "glory". And of course, "The Exorcist II:The Heretic", hands down the best time I ever had at the movies, the audience heckled the movie and my stomach hurt for a week from laughing at the comments. The one they claim is the "Original Cut" is NOT the same one I saw opening day. They cut a lot of the best (Worst) stuff out. My friend John and I laughed at the first "Exorcist" to the point people were looking at us like we were crazy. We just thought it was ridiculous.
