The one bit of this that actually interested me is "who for Deathstroke"... it definitely has to lay in the voice, but he has to be physically imposing as well. *five minutes elapse* I can't think of anyone but Ron Perlman. Put him in a suit and never show his fa-- HUGO WEAVING. Hugo Weaving as Deathstroke.
OOOOOOoooooooooooooo...Hugo Weaving as Deathstrokes voice is DEFINITELY a possibility but in my opinion Ron Pearlman's physically imposing body might be a tad overdoing it. Deathstroke should have Michael Phelps' physique as far as I'm concerned.
Edit: Ya know what...I don't mean to typecast the dude...but what do you guys think of Josh Brolin as Slade/Deathstroke?
Sorry, I'm usually more original that this=P
