The Hobbit : Dream Cast

[Sauron the White]

Ian Hom is not too old to be cast as Bilbo. The Ring kept his appearance relatively unchanged, so that the Bilbo we see in The Fellowship of the Ring is essentially the same in appearance as the Bilbo of The Hobbit.

Ian Holm looked and was great in Bilbo in all but a single scene - the one where he was much younger, is in the mountains and discovers the Ring. Sadly, that is the role for the entire HOBBIT movie. Holm looked badly made up in that scene. I cannot imagine a 77 year old man who has had serious health problems over the last few years performing a physically taxing role that the HOBBIT would require of him.

And Brian Blessed gets my vote for Beorn. The man is also a bit older but in great shape and is a mountain climber. Tremendous actor who could really get his teeth into that role ... sorry but I could not resist.
