Review of Decision Before Dawn

I saw this movie recently on AMC, and was extremely impressed. It was filmed on location only a few years after the end of the war, and uses the bombed-out scenery to brilliant advantage. I agree with all of the previous comments, and wonder why this film is not available on DVD or video. I was so intrigued by the story that I found a copy of the book on which it was based over the internet, "Call it Treason" by George Howe. I just finished it, and I enthusiastically recommend the book,it's worth searching for (out of print.) I wish there were more books and movies like this around....
