Art, I haven't seen the film, but read the books many years ago. Saw the film releases of both films and the extended versions on DVD. Here are some glimpses of what we might expect from ROTK, from an interview in the NYT with Jackson:

"McKINLEY But what of Tom Bombadil, the mysterious, wise tree-man in "Fellowship of the Ring" who never made it into either the movie or the extended DVD version?

JACKSON Oh, have you been harboring three years of anger?

McKINLEY Not anger, really. Just . . . disappointment.

JACKSON I always think of Tom Bombadil as a slightly silly character who doesn't actually contribute too much to the story. We've always felt the spine of the story was about Frodo and the ring."

As to Saruman being edited out of the final version, I thought this was already well known around the world? If not, here is a blurb from the Beeb from November about it:

"Actor Christopher Lee has said he was mystified to learn that his key scenes have been dropped from the third Lord of the Rings movie.
Lee, 81, who plays the wizard Saruman in the trilogy, said he had expected to appear in seven minutes' worth of climactic scenes.

"Of course I am very shocked, that's all I can say," he told ITV1's This Morning on Wednesday.

Lee fans have now started an online petition to restore the scenes.

"As far as I'm concerned, I'm only telling you this because it has been revealed on the internet, someone has talked and it certainly wasn't me," he told the UK TV show.

"If you want to know why you would have to ask the company New Line or director Peter Jackson and his associates because I still don't really know why.

"I can't say any more because I signed a confidentiality agreement and I honoured my word."

Asked if he would attend the première, he said: "No, what's the point? What's the point of going? None at all."

Personally, I didn't feel Lee's characterization of Saruman was all that great, so I don't know that I'll even miss him.
