Conan

I think if they were to try, another, reboot he could make a great Conan the Barbarian. Not endorsing the idea of another movie, just saying he would fit the role magnificently. He has the right colorings, dark hair and light eyes, close to the right height and a great combination of athleticism and size. It would be very hard to find a better fit, and just think on Vikings he is not even working out to be big he has stated in many interviews that they're avoiding looking too bulky or ripped to try to keep things more consistent to the period, he could easily put on a bit more mass to fit the role even better.

Once again no big fan of reboots, just saying he would be an ideal choice, and on top of that he's about fifty times the actor of anyone used so far.
