> “Before starting the series, we stuffed ourselves to the gills with Norse mythology, as well as almost every other type of mythology – we love it all! But you’ve got to remember that these are legendary tales – myths – and no two versions are ever exactly the same. We changed a lot of things – for example, in most of the myths Thor has red hair, Odin has one eye, etc. But we preferred doing our own version.”

Huh, did not know that. As an Icelandic person I knew about Þór the Norse god much earlier than Thor the marvel character. I never really pictured his hair color, nor knew he had a specific hair color in the mythology. I actually always pictured him with a beard though. What mostly mattered though was his characteristics. His ill temper and drinking habits, and the fact that he was not a nice person, nor a hero, but rather a guy who starts shit that gets everyone else in trouble, he also wins every fight except one (he looses one against Elli [the personification of old age]). The little I’ve seen of him in the Marvel movies, he keeps almost none of these characteristics.

EDIT: My favorite story of him is the depiction of the fall of Ásgarður, where Loki and some Jötun are about to use the gods vanity against them and con them out of stuff they cannot actually pay for a wall around Ásgarður. Þór, being the way he is, cannot be around a Jötun without fighting and killing him. So rather than paying up (which the gods cannot do) Þór is sent to see this Jötun, knowing very well that he will be murdered. This betrayal is marked as the beginning of the end in Völuspá (verse 26).
