Well, here's one thing I can say about Sam Worthinston. By virtue of his being a total non-entity, Sam Worthington is the only actor capable of making Giovanni Ribisi believable as a dynamic, menacing villain. Giovanni Ribisi. From Friends.
Hemsworth also stars in another 'franchise' called Huntsman. Huntsman movies are not about former Utah Governor Jon Huntsman, though that would likely be more interesting than what they are about. Huntsman is a made up white male lead added to the Snow White fairy tale for no reason at all except as an excuse to cast another bland white man to star a fantasy action movie that no one will ever care about or remember.
Snow White and the Huntsman came out a few years ago. This spring, a sequel appeared entitled Huntsman: Winter's War. That's right, Hollywood made a sequel to Snow White without Snow White because I guess these days there are too many movies coming out starring women. Instead the movie stars Chris Hemsworth as Huntsman. Huntsman, who fought in Winter's War and ran for the Republican nomination for president in 2012 but lost to Mitt Romney.
