The movie 300 is a review about the 2007 film that depicts the Battle of Thermopylae between King Leonidas of Sparta and his 300 soldiers against the Persian army. The review discusses how the movie portrays the military effectiveness of Ancient Greece and how Sparta's King Leonidas rallied his army of 300 men to challenge the invading Persian forces in a desperate attempt to delay their advance.
