Hmmm too many hard choices....
Clive Barkers Lord of Illusions ... IMO a truly underrated flick... the imagery and story I find fascinating and unnerving. Particularly with the gospel classic "While the Blood runs warm in your veins" is playing...too sweet. I will admit a fondness for much of Barker's work...
"I was born to murder the world"
Night of the Living Dead (the original, tho the remake is decent and I like it as well) ... first saw this when I was around 6 and it still stands the test of time.
"Their coming to get you B..a..r..b..a..r..a.."
Evil Dead ... Another true classic I feel, something about the blend of horror and humor was just perfect.
"...It got into my hand and it went bad. So, I chopped it off"
So many I truly love, but they strike to the bone atm.
Note: Also a strong nod to odd and rare flicks like Begotten and 120 Days of Sodom...truely...just...over the top.
Sorry for any misquotes, but didn't check their exactness.
