Roughly chron order. I couldn't possibly do them in order of preference:
Rear Window
12 Angry Men
The Hill
Dr Strangelove
2001
Quatermass & The Pit
The Taking of Pelham 123
Jaws
Close Encounters
This Is Spinal Tap
Withnail & I
The Double Life of Veronique
A Short Film About Killing
The Village
V interesting lists. Some great films mentioned. I have to admit I found it hilarious that someone had Cocktail on theirs, but I'm not taking the p*ss - good on you, it's what these lists are for.
