Oh geez. Joaquin Phoenix I would not pick, simply because he gives me the creeps. Maybe it's the roles he's chosen, but there's something slimy about the guy that sets my teeth on edge. For me, although Turin is dark and overly obsessed with his own history, there's a core of goodness in him that is overwhelmed by fate, and that makes him a character that I sympathize with despite his tendency to shoot himself in the foot on a regular basis. And I just don't get that from Joaquin.

Oded Fehr is wonderful, and I'd love to see him in any Tolkien film. Jude Law? Eh. Overrated, in my opinion. Beleg I'd have a hard time casting. It should be someone unknown, I think. Elves having that veneer of perfection (at least compared with Men), I think it would be distracting to cast someone that's too familiar.
