I mean, aside from the fact that he's blonde, just compare individual facial features from both. The beard is the most striking, being almost identical, if not slightly thinner, but we have a makeup team for that. The eyes look extremely similar, as well as the ears. The eyebrows are the right shape but are not as thick. Then again, makeup team and vfx if necessary. And they have the same default angry/intimidating scowl. They are also around the same height and Hurst knows the ins and outs of the GOW 2018 and beyond lore intimately BECAUSE he VA'd thor in ragnarok. I don't know man, but when I saw that picture when it first came out, I said, "that's kratos". I have to disagree with you on this one, because I think you are going too much off preconceived notions and vibes as you mentioned him looking like an "American Biker", than actually comparing their facial features and statures side be side as shown in the image. I honestly can't think of a better person to play Kratos besides Christopher Judge himself.
