Thor: Love and Thunder looks set to follow the comic books by having Jane Foster become the Mighty Thor. While plot details are few and far between, we have been able to figure a few things out thanks to set photos, including the fact that the original Mjolnir somehow re-forms and grants Jane her powers.
It's unclear what this transformation means for the God of Thunder himself moving forward, but going from scientist to superhero resulted in quite a few changes to how Natalie Portman approached the role.
Talking to Vanity Fair, the actress broke down what sounds like an intense workout routine.
"It was really fun. I worked with a trainer, Naomi Pendergast, for, I think it was, four months before shooting, and then obviously all the way through filming. We did a lot of weight training and a lot of protein shakes - heavyweight training that I haven’t ever done before. Of course, I’ve never really aimed to get bulky. It was very physical, so it was a lot of both agility work and also strength work."
As for how undergoing that superhero transformation affected her performance in Thor: Love and Thunder, Portman added: "It definitely helps you get into character, and it’s definitely changed the way I move. You walk differently; you feel different. I mean, it’s so wild to feel strong for the first time in my life."
There are plenty of fans hoping that Jane sticks around as this version of the Mighty Thor, but it's also possible the change will be a one-off. It likely depends where the God of Thunder's story heads in this fourth chapter, because a villain as fearsome as Gorr the God Butcher likely means not everyone is going to make it out of this one alive (something that the whole "God Butcher" thing alludes to).
Thor: Love and Thunder is set to be released on May 6, 2022!
