Thor hit the big screen for the first time in 2011 and proved to be the breakthrough role for Aussie actor Chris Hemsworth.

Thor saw Kenneth Branagh back in the director's chair as he tackled a CGI driven blockbuster movie for the very first time.

Natalie Portman, Anthony Hopkins, Tom Hiddleston, Stellan Skarsgård and Idris Elba were all on board and the movie was a huge hit as it took over $449 million worldwide.

Later this year Thor: The Dark World will be released and will see Hemsworth reprise the title role.

Christopher Eccleston is one of the big new additions to the cast list while Alan Taylor takes over the director's chair.
