It's the sequel that reinvented both the character and the franchise, so let's revisit the cast and characters of Thor: Ragnarok. When Marvel first announced their plan to make a cinematic universe out of their lesser-known superheroes, the industry greeted the idea with intense skepticism. Even when 2008's Iron Man proved to be a huge success, it remained to be seen if audiences would accept a seemingly outdated character like Captain America or the fantastical elements of Thor.

History proved Marvel was right to take the gamble, with the MCU soon inspiring other studios to seek out their own cinematic universes. Chris Hemsworth has grown into the role of Thor over the past decade and even when solo entries like Thor: The Dark World proved disappointing, he always brought charisma and humor to the character. Thor: Ragnarok proved to be a major reinvention of the character and put more of an emphasis on humor and colorful action.
