Thor: The Dark World will more than likely pick up a little more cash when it opens in Japan not too long from now, but it seems as if the sequel will finish its run at the worldwide box office with a cume of just over $600 million. That's a hell of a result for the sequel, and while it doesn't come close to Iron Man 3's $1.2 billion, it's surely enough to guarantee that we'll see the God of Thunder back on the big screen for another solo movie after The Avengers: Age of Ultron.
