Blanchett is playing Hela, the villain in Thor: Ragnarok, which will be the second time that the main antagonist in a Marvel film is a woman.
Ragnarok is in the final weeks or even days of production, which means Blanchett could have already finished her role and it sounds like she had a blast.
Marvel Studios is currently in the business of getting the most recognizable names in Hollywood to join the MCU.
Taking a look at some of their most recent castings will prove that they are being fairly successful in doing so, and one of those names would be Cate Blanchett.
