So this thread has turned into a crappy Sam Worthington Avatar rant.
Look both are weak and crap. Worthington can't act at all, Avatar was a lazy predictable film with nice shiny cgi that is it, it has not changed cinema for me, I wasted 3hours of my life on a crap movie.
Now back to Thor, Chris won't need cgi muscle he has always been a big guy and I'm sure he has bulked up alot since the last picture I saw of him on here, all he needs really is longer hair and maybe a beard. He is tall enough he has a deep voice that will add to the depth of Thor's words mostly when he shouts.
Can't wait for a proper teaser pick to come out, more excited for Thor than I am for Cap .. that looks like it maybe a mess as they are really dragging the casting out with some odd choices.
