You can find a lot of cut scenes on Youtube, but the problem is the decision to go from 3-hour epic to 2-hour feature was made about mid-way through the production, so we really won't ever see what was truly cut, because it never got shot in the first place. Dune could have been a proper masterpiece if the producers let Lynch geek out with a 3 hour cut. Instead we have the first half of a very gorgeous and interesting movie with a wonderful slow-burn leading up to something then... a sudden "Oh god, we have so much story to finish," second half that feels entirely too rushed for its own good. The non-canonical ending could have been workable with enough exposition and justification, but as-is completely comes out of nowhere and caps the mediocre 2nd half with a nonsense ending few walked away from happy.
