The trailers I have seen on Jarhead, the new movie with Jake Gyllenhaal, look promising. I have high hopes for this movie, even while having severe fears about the political cheap shots they will take. The movie is based off of a book written by a marine sniper, which is his account of his time in the first Iraq war. BTW Jake was in Moonlight Mile, which I thought was a good movie, though I had never head of it until I rented it. Jarhead also has Peter Sarsgaard, another one of my favorite actors.
I am hoping that they have some good training scenes, war room scenes, and some awesome action. I personally think this movie is going to be better than Blackhawk down, the last, best war movie I can think of. I doubt it will be better than the Band of Brothers series that aired on HBO (but then again, I cannot name one war movie that I thought was better than Band of Brothers).
BTW Sandcastle, Band of bothers is really cool you should buy that and watch it.
