HBO made a movie called "When Trumpets Fade." It was about the battle of the Ardennes Forest. Very well done in my opinion.
The other movie that didn't make their top 20 was "Hamburger Hill." Amazingly accurate according to someone I once worked with. (said he was there...I don't know, but I thought it was a well done movie.)
Probably my all time favorites would be "The Last of The Mohicans", and "The Sandpebble." ("Blackhawk Down" and "We Were Soldiers Once" get honorable mention)
I must have missed When Trumpets Fade but I will watch for it. As to Hamburger Hill, I was on the Left Coast trying to peddle some of my screenplays and went to the postproduction screening of 'Hill' with a buddy of mine more connected in the screen trade than me. I found the film very realistic for the times, very patriotic and very moving. When the film, ended, I stood up and applauded. I was the only one doing so. My friend pulled me down, saying, "Stop it! Don't get the liberals on my case!"
The film was released without any studio backing and thusly did poorly at the box office.
BTW My friend is out of the biz now and currently breeds dogs up near Reno... Sal, I know you are not lurking here, but I just had to say, "Hi!"
