So the costumes, arms and armor may not have been completely historically accurate, but I'm sure they had budget concerns so they went with what was the best bang for the buck. MRL's not horrible, just that it is more anachronistic than historic- keep that in mind and you're good.
I've gotta get my copy of the re-released Arn: Knight Templar from Amazon, looking forward to that!
Your Highness was funny, crass and boorish funny, but funny nonetheless. As I'm a Natalie Portman fan, any movie she's taking her clothes off is reason enough for me to watch it. lol
