There were actually 1,300 defenders. 1,000 plus the 300 Spartans. I haven't seen the movie but historical accuracy isn't Hollywood's forte.
From the commercials I have seen of the movie trailer the Spartans look a bit like professional wrestlers and not the elite special forces that they were.
Hulk Hogan and Gorgeous George were there?
Regardless, it is a dramatization and a very enjoyable movie. The first thing I did when I saw it was coming out was go and review the actual history behind the battle because it made me curious.
Are you one of those people who likes to brag about never going to see a movie since the 1980s?
