Thor: Love and Thunder will feature the return of Natalie Portman as Jane Foster, though with one major upgrade.
At Marvel Studios' presentation during Comic-Con International in San Diego, Thor: Ragnarok director Taika Waititi revealed he was drawing inspiration from Mighty Thor for his upcoming film. That's when Portman took to the stage, revealing she was returning to the Marvel Cinematic Universe and confirming she'd be becoming Thor herself.
"So for us, there's only one person who could play that role, please welcome Natalie Portman," said Taika Waititi as he introduced Natalie Portman to the stage.
Portman made her debut as Jane Foster in 2011's Thor, and reprised her role for the sequel. However, she didn't appear in Thor: Ragnarok, with Portman having seemingly parted ways with Marvel Studios. In that movie, Thor revealed he and Foster had broken up, explaining her absence from the film.
There's precedent for Jane Foster becoming Thor as, in the comics she held the mantle for several years starting in 2014's Thor #1. It's unclear what this might mean for Chris Hemsworth's version of the character, though the process of losing his title definitely caused him to undergo some major development in the comics.
In addition to the return of Portman, Hemsworth will return, as well as Tessa Thompson. It's unclear who else from Thor: Ragnarok might return.
Thor: Love and Thunder arrives in theaters November 5, 2021.
