10 Biggest Casting Mistakes In MCU History
9. Natalie Portman (Thor And Thor: The Dark World)
Actors tend to join projects based on something they are passionate about within the material and set-up offered them. In 2019's Joker, Joaquin Phoenix stated how he fell for director Todd Phillips' iteration of the character and the film he wanted to make and mentioned how he'd be open to exploring the character further if Phillips was attached.
That's why when eventual Wonder Woman director Patty Jenkins was brought on board to helm Thor: The Dark World, Natalie Portman was understandably excited about the prospect of being a part of the first MCU project to be directed by a woman.
Jenkins would then be given her marching orders due to creative differences and Portman felt as though she'd been cheated out of the project she signed up for.
This led to Portman choosing to not be directly involved with any Marvel films post Dark World and Marvel gifting themselves with the headache of having to tiptoe around Jane Foster's involvement in any other MCU outing.
In 2019 Marvel did announce that she would be back for the fourth Thor film, Love and Thunder, but Portman's feeling of betrayal wrote Marvel into a hole they spent years trying to dig out of.
It makes you wonder what appearances Jane Foster could've made in the MCU had this not been the case and she'd been played by a different actor...
