I did exactly the same thing as some of you guys, I thought it was Charlie Hunnam when I first saw the promotions for Vikings and looked it up only to find out it wasn't. Definitely a lot of similarities between the characters though. Both care very much about their people, but can be extremely violent and brutal in nature as well especially when it effects them, or the people they care about most.
