Whoever is the warrior , will be the main character of the movie. Like Anthony Hopkins playing Thors dad sure he did a decent job , but in movies of these nature old people can't be the main character or more than 20 mins on screen.
Arnold would look like a Parody of Conan with a sword riding a horse and trying to knock out a camel with a single punch. Lol.
