This guy shows some potential. He's listed at 6'6" I think. Name is James Preston Rogers.
Good find. Thor IS a tall character. Still, I don't think Thor would make a good movie; many people are simply not familiar with him. He is really from another dimension (Asgard) and if you are not a comic book geek, his origin may be hard to follow. Introducing him to the modern world would require so many changes to his storyline that he would be a lot less interesting.
Thor's primary enemy is Loki; Amora the Enchantress is another frequent foe. Both have histories and motivations that would be complicated and expensive to bring to the silver screen. Similarly, can you tell Thor's story without including Odin?
Have there been many Thor cartoons over the years? I don't think so. Prepping the public with a history of animated adventures makes for an easier retelling on the silver screen. Superman, Spiderman, X-Men, Fantastic Four, all have that history; Thor does not. I think the best hope for a Thor story is to have him appear as a cameo in another movie (Fantastic Four or IronMan for example) then use that appearance as a stepping stone to his own feature film.
He's getting old now, but a roided up HHH had Thor potential.
