Gandalf Vs. The Witch King

[The Saucepan Man]

Obloquy, it is quite clear from Tolkien's Letters that he perceived LotR, the book, to be, partly at least, concerned with the "ennoblement of the humble", the weak prevailing over the mighty. I don't have the Letters to hand, but there are a number of quotes to that effect. Whether he intended this from the outset is less clear, I believe, but it was certainly part of his perception of his own work. And, regardless of whether you share that opinion, it is clearly open on the material for readers to perceive it in that way.

Quite what this has to do with the portrayal of the confrontation between Gandalf and the Witch-King in the film, though, I have no idea.
