Movie fans were transported to Asgard in the 2011 film "Thor," directed by Kenneth Branagh. He was born on Dec. 10, 1960.
The movie was based on stories published by Marvel Comics. But before he was a superhero, Thor was a Norse god.
According to Norse mythology, there were nine worlds that made up the entire universe. Asgard was home to the gods. The mortal world which we know as Earth was called Midgard. The other worlds were home to various other creatures such as elves, dwarves and demons.
We'll get to see more of those other worlds next year when the Thor sequel hits movie theaters.
