Conan
The character created by Robert E. Howard has been mishandled in an otherwise great movie starring Arnold and in the most recent POS.
I think what they need to do is more of what they almost did- adapt one of the stories as a direct to video animated movie. That movie, Red Nails, was stalled due to funds. And Ron Perlman was set to voice Conan. But I think Jason Isaacs would be better. And here's a quote that I think he would kill delivering:
"[The] chief [of the gods of Cimmeria] is Crom. He dwells on a great mountain. What use to call on him? Little he cares if men live or die. Better to be silent than to call his attention to you; he will send you dooms, not fortune! He is grim and loveless, but at birth he breathes power to strive and slay into a man's soul. What else shall men ask of the gods? ..."
Honestly, I think if Isaacs were younger and you gave him six months to hit the gym like a maniac and some clever camera angles to make him look taller, he'd actually be good as the character in the flesh, as well.
