One that I don't think has been mentioned: The Tenth Man

It starred Anthony Hopkins

Stalingrad,das boot are great.

I didn't think that there were any more left, but I haven't seen the titles, On the Beach, Hunt for Red October; The Good, the Bad and the Ugly; and perhaps the capstone piece defining the consequences of war: Judgement at Nuremberg.

"Paths of Glory" with Kirk Douglas is #1 for me. Also "The Dam Busters" and "The Cruel Sea". The British know how to make good war movies!

The best have been mentioned, but I would like to add the following to the list:

Breaker Morant
A Midnight Clear
Zwartboek

It seems to me that quite a lot of first class war films have not been listed yet? In fact as I go through the lists above, with the exception of ‘Zulu’, ‘Cross of iron’ and ‘Kelly’s heroes’ none of my favourite war films are in anyone else’s post.

How about:-

1)The battle of Algiers - My all-time favourite war film it shows terrorism and security to be two sides of the same coin.
2)In which we serve – Noel Coward does his Mountbatten impersonation with excessively stiff upper lip. Wonderful stuff makes one proud to be British
3)Land and freedom – Second best film about the Spanish Civil war from the perspective of the Brigades.
4)Pan’s labyrinth – Best film about the Spanish Civil war and it has fairies too!
5)Grave of the fireflies – Anime about the American firebombing of the city of Kobe from the view point of a small boy
6)Days of glory – Magrebien soldiers fighting for the Free French.
7)Come and see – Harrowing, the partisan war on the Eastern Front through a young boy's eyes.
8)The sand pebbles – Anti-colonial film set on a US river gunboat in China between the wars.
9)Black book - A young Jewess tries to stay alive and joins the resistance in WWII Netherlands, the title is presumably a pun on THE black book. Shades of grey everywhere, not for people who are only comfortable with simple good vs. evil ideas.
10)Soldier blue – This Western is an allegory and the best of the anti-Vietnam war films.
11)Revolution – The American war of independence from the view point of an ordinary man and his son caught up in events.
12)The charge of the light brigade – The 1968 version. Heaven alone knows how many horses they killed as they used hundreds of trip wires rather than trick horses. The colour and the dashing uniforms are an interesting counterpoint to the futility and carnage of the charge.
13)One man’s hero – The Irish Saint Patrick’s Battalion fight to defend Mexico from invasion by the USA, are defeated and hanged by the victors.
14)The opium wars – A fairly even handed perspective on the opium wars from the Chinese. Somewhat different to the 'good old Royal Navy spanking the upity Chinese Mandarins' view I got from school.
15) The odd angry shot – One of the few good Vietnam war films. This one is about a group of Australian conscripts. There is a strong vein of very dark humour running through it that appeals to me.

Whups! On review I notice someone has already mentioned ‘Black book’ by its Dutch title and ‘The charge of the light brigade’ (but not which version) but I don’t think I shall revise the post. I’ll just add another two film that I think are good and with the other three at the begining other people have mentiones that should bring the total up to twenty in all:

19) Escape from Sobibor – I list this not because it is a particularly good film but as a reminder that not everyone went to their deaths in the gas chambers as sheep without hope.
20) The one that got away – A film that added a phrase to the English vernacular ‘Going Hardy Kruger’ for running away or hiding from work.
