It was previously teased by Natalie Portman that Thor: Love and Thunder is "gonna be really silly, and funny, and great," and the actress has now revealed some new details about the film.
Appearing on The Kelly Clarkson Show, Portman told Clarkson that she won't be called 'Lady Thor.' "So, she does have powers. It's not exactly the same as Thor, it's her own version of it, and... she's called the Mighty Thor."
As part of Jason Aaron's 2018's Death of the Mighty Thor story arc in Marvel Comics, Jane Foster gains powers nearly identical to Thor's after the Odinson becomes unworthy of wielding mjolnir and Foster becomes the mystical hammer's owner. This admission from Portman appears to indicate that the Taika Waititi film might be heading in a slightly different direction.
Prior to Foster acquiring the powers of Thor in 2018, the character was previously fused with Lady Sif in a 1975 storyline from Gerry Conway after an entity known as Fear tricked Foster into a suicide attempt. Knocking on death's door, Sif chooses to sacrifice herself by giving her life force to save the lover of the man she loves.
Another possibility would be Portman's Jane Foster becoming a Valkyrie, a recent development in the comics that came about after an attack on Manhattan by Malekith. As part of her new Valkyrie powers, Foster gains a golden mace, chain and wings.
Portman is currently in Sydney, Australia to prepare for filming. Thor: Love and Thunder is scheduled to hit theaters on February 11, 2022.
