Just to be different from all the epic moments everyone else is listing I'll pick one that was unintentionally hilarious in a sad stupid sort of way.
It was the 3rd movie when the enemy brought out the huge mutated battle elephants against the human army. As the king sees them he yell to his troops to reform the line. As I was watching him do this I was thinking "Oh good god please don't do what I think you're about to do. Please don't charge directly at the elephants so they can easily squish all your men+horses." But as we all know that's exactly what happened, it was like that episode of Futurama when everyone except Fry became stupid and the mayor of NNY ordered more trains to help deal with the other trains not leaving their train stations and creating train wrecks, except obviously LOTRs wasn't trying to be funny. It was one of those so stupid you can only laugh at it moments, and is one of the first things that come to my mind whenever someone mentions LOTRs.
