Thor: The Dark World is the sequel to Thor, or more accurately the latest film set in the Marvel universe, which like Iron Man 3 continues its story following on from the events of Avengers Assemble.
It’s hard to think of another film series like that which Marvel has tried to create in recent years. Arguably the X-Men universe comes close with Wolverine and X-Men:First Class spinning off from the original trilogy of films, however, there’s something more purposeful and sure-footed about everything Marvel is doing.
It probably says something that financially the least successful character of the series, The Hulk, is also the most well known. Iron Man, Thor, and Captain America were not household names prior to their big screen outings, and certainly far less popular than A-Listers like Batman, Superman or Spiderman. However, Marvel has made us think of them as big players now, and this is the context in which Thor comes bounding onto our screen.
