Saving Private Ryan
Where Eagles Dare
Full Metal Jacket (it's almost like 2 films in one. The first bit is just fantastic when they're in bootcamp. Gunnery Sergeant Hartman's performance was perfection.)
Come and See
The Ascent (a wonderful companion piece to Come and See that was directed by Larisa Shepitkov - Klimov’s partner)
The Sun (about Hirohito)
Battle for Algiers
The nine hour long Human Condition Trilogy (about the occupation of Manchuria told from the perspective of Masaki Kobayashi, a director who loathed Japanese militarism), and Fires on the Plain (an adaptation of Shohei Ooka’s stunning, Ballardian novel), are also movies that I would recommend to those who like this genre of films.
