Many good ones were already mentioned
But from memory:
- The snatch
- The big Lebowsky
- Clerks
- American Psycho
- 2001 a space odissey
- Blade Runner (possibly the directors cut)
- Apocalypse now (possibly the redux version)
- Full metal jacket
- The godfather (first 2 movies, the rest is not as good)
- Fight club
- Alien
- The Truman show
- In the mouth of madness
- They live
- The terminator (first 2)
- Animal house
- the dollar trilogy from Sergio Leone
- Once upon a time in America
- pulp fiction
- reservoir dogs
Assuming good faith, that's a hell of an assumption
