He would have been great, I agree! Unfortunately, he's been cast as Oromë. http://forums.signumuniversity.org/index.php?threads/results.231/
Oh the multitude of details....Alas! I definitely forgot that little detail.
I like the emphasis on the fatherly, an interesting suggestion. Beleg is supposed to be one of the older elves.Paul Bettany would be my second pick. I know there have been suggestions for him in other roles but while he's not officially been cast for anything yet I'll just put it on the table. Pretty much for the same reasons as Skarsgård but more emphasis on the mentor/fatherly part, appearance-wise.
