I know, but the acting was superb I thought. I haven't a clue where they are going to go in season 4 as it starts in the 90s with the advent of the first web browsers.
What, as an actor? You'll probably need to do a drama degree, then pimp yourself round repertory, TV commercials and go for every audition you can find. Good luck.
Vikings 4 seasons so far and a 5th on the way.... best thing in ages. Well worth watching from the start.
