Meh. They're the same height and have the exact same nose, but the other eye-catching similarities (same hair color, same haircut, same beard/stache, same regal countenance) are superficial. If they had different haircuts, shaved faces, and were captured in a more candid scene, I'm not sure that we'd see much of a similarity.
Here's another image[0] of them in which they look less like twins (ignoring the over-the-top superficial similarities). [0]https://cdn.images.express.co.uk/img/dynamic/106/590x/King-G...
