Vaughn recently talked with Empire about how he became involved: "When I went into Marvel for my first X-Men meeting, I saw a figure on the desk and said 'are you guys are going to make Thor?' They said, 'We're just going to commission a script. We want to do it like Gladiator with Norse mythology and the birth of a superhero'. That really stuck in my mind. And when Marvel saw Stardust, they asked me to do it. So here I am, back again and prepping Thor."
For the uninitiated: Thor is the son of the God Odin, and a little bit of a bad-boy, so dad decides to teach his son a little humility by placing him on earth as a surgeon. Once there, Thor no longer remembers his divine origins, but he does develop the power to transform back and forth (eventually the series did away with the alter-ego altogether). Vaughn has confirmed that there is not going to be much crossover between the Norse and Marvel mythology, saying: "...You've got Thor and Odin and it's set in Asgard - it's not going to be like Lord of the Rings or even Narnia. I think it's important to keep it comic book. We're not doing the Thor of Norse mythology. We're doing the Marvel Thor." We already know that the looming threat of a strike has placed the flick on the fast track, so stay tuned for any updates that come our way.
