Mr. Moore
He was one hot teacher! At the end with the long hair and armour, he was totally swoon worthy. His voice is pretty damn sexy too.
EDIT
Opinions change. Not a fan of his actor anymore for various reasons...
I know how you feel. As Mr. Moore, he looked nice enough, just your average well-dressed history professor, but when he transformed into Mordred, wow, smokin' hot Arthurian legend baddie right there. This was a cute movie. I wouldn't call it a great introduction for kids into the King Arthur legends, but it was entertaining enough.
Nevermore!
