Again, Hasbro/Toy Biz rarely ever made anything after comic book characters actual looks, like that Coipel's Thor. Only the uniform itself is pretty much the only accurate thing, as every single comic book artist also draws characters differently... who also model characters after real life people (whether it's people they know or porn actors, who knows).
