* Alexander Skarsgård: He was a frontrunner for the role and even tested for it. He has gone on to have a successful career with roles in "True Blood" and "Big Little Lies."
* Tom Hiddleston: Yes, you read that right! The actor who would become Loki was actually in the running for Thor. Ultimately, the filmmakers felt he was a better fit for the mischievous god of mischief.
