Interesting you bring this up. When I first saw this thread I wondered why doesn't Hollywood make a movie about acient Greece that dealt with something other than Alexander or Troy. I thoght, boy the battle of Thermopylae would make a great movie. Three hundred of the toughest Spartans defenting a mountain pass in a rear guard action against more than 200,000 Persians. They were on a suicide mission to delay the Persians for a day while their main force could retreat and regroup. These 300 soldiers held off the Persians for seven days and fought until the last man was dead. They took out anywhere from 20,000 to 30,000 Persians in the process. That would make a great movie.
While I was thinking about this I read your post and see that there is a movie about this in the works. Based on your recommendation I bought Gates of Fire on Wed., started it about 6:00 and didn't stop until 4:45 AM, when I finished it. Great book and thanks for the tip.
The Colin Farrell/Bruce Willis WW II movie I mentioned in Post 108 is "Hart's War".
