I've been hearing Warwick Davis rumors, too. I'm sure he'll be involved sooner or later. As for Saruman, "can" and "will" are two different things. A number of talented actors out there *could* play the role as you say, but how many would think to if Peter Jackson doesn't? Ideally, he should think of this in the first place.

At any rate, you've sold me on Anthony Hopkins. He's arguably my favorite actor working today. The ease at which he turns in spectacular performances reminds me of Spencer Tracy. I rarely come away from a movie starring either of them without being impressed anew at their talent and charisma.
