Lord of the Rings: Return of the King.
Great film, some memorable scenes. I like the scene where Gandalf beats up the Steward of Gondor, and all the guards just watch. I also like the scene where Gandalf rides out to protect the Rohan Rider's from the Nazgul's, and is referred to as the white rider.
My favourite part is the final sequence of scene's, it's both dramatically upsetting and happy.
