1. Das Boot Probably the best war movie ever, imo
2. Saving Private Ryan Don't think there is a film like it that's so graphic (at the beginning)
3. Dr. Strangelove Cold War, funny yet cynical
4. Kellys Heroes Funny as hell. Good 'ole Oddball
5. Dambusters Saw it again recently, forgot just how good it was!
Also:
Angels 1 5 - Very good film that not a lot of people have heard about.
All Quiet On The Western Front
Gallipoli
Memphis Belle
