I just saw this movie and i loved it, first of all its very low budget. The whole thing was done on a green screen and although it may sound rubbish the overall effect is really good.
The main characters are 5 pretty crappy Spartans who weren't at Thermopylae, instead they were given the task of guarding the secret goat pass, which they fail to do resulting in Leonidas and the 300 dying. They then become the laughing stock of Sparta and now Claudius, Darryl, Demetrius the Blind, Shazaam and Testicleese have to go on a heroic journey to show themselves as true Spartans with no weapons and no brains. Just the desire to prove themselves as warriors.
Its a great comedy with loads of laugh out loud moments and a really hot girl. It has a big internet following and a growing amount of fans. Well worth watching in my opinion.
