I saw this movie when it first came out in 2009, I believe, when I was just a kid and it is still one of my favorite movies of all time. As I got older there were a few mistakes in it that I noticed. One was, someone in the movie said that the Spartans fight like Machines. I don't think that the word machines or machines in general were invented then. I could be wrong though. A few other flaws but in my judgement it is one the finest army action fighting movies.Reading history books about the Persian wars it seems quite accurate.
