the directors Cut of Das Boot truly rules
i mean,.. get the dvd, but it into a nice surround setup, and set it a bit loud.. the sound of the boat, when its getting under pressure is really amaring
anyway, other great movies ive seen:
The thin Red Line
enemy at the gates ( maybe not entirely accurate, but still a nice movie)
U-547 (not entirely shure about the number tough.. but you know, that bon jovi movie )
Saving Private Ryan
Memphis Belle
those old movies like a bridge to far. (but im shure you all mentioned them already
and espeacially not to forget. (just got the series myself)
Band of brothers (thats i a 10 episode series.. but it's totally awesome, and historical correct )
