Does anyone else think Richard Armitage would be AMAZING as Bard? He has the perfect "grim", noble look and manner Tolkien describes. Check out his IMDB: http://www.imdb.com/name/nm0035514/
And for those of you who have not seen him act, here are some clips:

Other than that, my casting preferences are DEFINITELY Ian Mckellen for Gandalf, Andy Serkis for Gollum, and Martin Freeman for Bilbo. (Dent Arthur Dent! It's perfect!!) I would also like to see Liam Neeson as either Elrond or the Elven King. And if they don't get Richard, Gerry Butler would also be good for Bard.
