I understand that the casting call was for a young Henry but the physical traits/attributes are so completely different between the two. He’s more than a foot taller and extremely thin. Skeletons don’t match up. LOL! Just doesn’t make any sense.
I’ve seen other photos of the actor for Young Henry, and he actually does share a few physical traits to the Older Henry we have seen. Look at the face in particular. I think it’s just hard to imagine someone elderly looking as a young man.
