Matrix and LOTR series are good. I am a fairly big war movie fan though. Saving Private Ryan, Enemy at the Gates, U-571, Behind Enemy Lines, We Were Soldiers, Pearl Harbor, K-19: The Widowmaker, The Thin Red Line and Black Hawk Down are a few of my favs.
edit: O ya and Full Metal Jacket - it a very good and brutally savage movie as well. :amazed:
