This film is absorbing because you are kept guessing until the very end. Hart, the lead character, isn't exactly an angel; and the Nazi Kommandant conjures up a measure of sympathy, with other motives of characters such as Col. MacNamara (Willis) truly unclear until the end.
Thus, it's enough to keep you watching, although I wish I'd read the book first. Also, it's not an "action" film in the Schwarzenegger sense, but it is fast-paced and holds your attention, as the plot keeps twisting and turning.
Contrary to what others thought, I found HART'S WAR to be reasonably historically accurate. It's frequently pointed out that by late 1944 / early 1945, the Germans were reeling, desperate and disorganized, while HART'S WAR portrays them firmly in control. This is a fair criticism, but I would respond as follows:
1. HART'S WAR coincides with the Ardennes offensive (Battle of the Bulge), which was the last major German offensive of the war and which came perilously close to succeeding. Puffed up from that near-victory, not knowing (as we know today) that this was the last gasp of a dying reich and not a turning point towards victory, and now holding hundreds if not thousands of Allied POW's to boot, it's no surprise that the Germans are still confident of victory.
2. Also, HART'S WAR takes place in a short period of time (I would guess 2-3 weeks between Hart's capture and the end of the trial, which itself is only a week). The story does not drag into the spring of '45, at which point the Germans knew they were losing.
3. The Nazi Kommandant epitomizes this German confidence, yet because he was educated in the US, he has at least a measure of sympathy for his American prisoners and treats them with an equal measure of military courtesy, with a few exceptions. Other Kommandants during this time may not have been as "humane," but, because of his background, Visser's lack of brutality (again, with exceptions) is understandable.
Bruce Willis is clearly a supporting actor in this film, but I felt he had a strong and important role and was, arguably, the CENTRAL character while Colin Farrell is the LEADING character. However, Willis gets top billing for one simple reason -- TO SELL TICKETS. It worked for me, at least.
