I’m not a huge movie fan, but I want to broaden my horizons a bit. I’ll offer my list (that I’ve rewatched so many times I’m a bit tired of them):
- 
Young Poisoner’s Handbook
 - 
Full Metal Jacket
 - 
Life of Brian
 - 
Holy Grail
 - 
Sunset Boulevard
 - 
Curse of the Golden Flower
 - 
The Nightingale
 - 
Downfall
 - 
Amadeus
 - 
Once Were Warriors
 - 
Dusk to Dawn
