Day Zero - 2007

I don't know on this one. A good movie, the actors were all good, yes, but the story is tough, and I doubt it very much I'll ever see it again.
Three friends receive orders to prepare to join the war, but they're not soldiers, and are not prepared for this. In the 30 days they have to prepare themselves, we see how they deal with it, their friendship, their personalities, their problems. There's one who's afraid and doesn't want to go, but of course he has to. Another one at the beginning appears like he's not too much troubled by this, but them things happen and he starts caring, and also wouldn't want to go. Elija Wood plays the third friend, who at the start is all about duty, and we must go, and stuff like that, but as days go by you can see he's kind of losing it. In the end, he can't cope with it, and kills himself when day zero finally comes. That was really tough, a real blow.
The other two friends then leave for war together.
It was very intense, so thank you but no more, now I've seen it, no repeats are necessary.
