Jane Foster wields a broken Mjölnir in Thor: The Dark World. Now, she's set to become a superhero herself, assuming the persona of Mighty Thor. However, her mystical hammer appears to have been broken and just patched back together, an observation that has since been a point of conversation for the public.
Director Taika Waititi marks his MCU return with Chris Hemsworth's fourth solo film as the God of Thunder. Following the success of 2017's Thor: Ragnarok, which both revived the sub-franchise and revitalized fans' interest in the Avenger, Marvel Studios teaming them up again for Thor: Love and Thunder only makes sense. Waititi is going bigger with his film by assembling an expanded ensemble that includes some of the Guardians of the Galaxy, in addition to the debut of Russell Crowe's Zeus and Christian Bale's villain, Gorr the God Butcher. Arguably, the most exciting part of the flick is Portman's introduction as Mighty Thor.
Marvel Studios has purposefully kept details of her arc in Thor: Love and Thunder under wraps. While fans wait for the film's official trailer, new tie-in merchandise offered the best look at Thor: Ragnarok. Somehow, it was put back together, perhaps with the help of other Asgardians - or maybe even master blacksmith, Eitri (Peter Dinklage), who created it in the first place.
In Thor: Ragnarok, after Hela destroyed Mjölnir, it didn't seem like anyone took the time to gather the pieces of the broken hammer. However, it's also worth noting that after the events of the film, Valkyrie (Tessa Thompson), Korg (Taika Waititi), and half of the Asgardian refugees settled in the same place while The Avengers, which is in the same country as where New Asgard has been established.
Whatever the case may be, it's clear that Marvel Studios want Jane to wield the same Mjölnir that Thor used before. This makes sense as taking another hammer from another reality, while possible, sounds like a lazy way to execute Mighty Thor's arc. Although the MCU is actively tackling the multiverse at this point, Thor: Love and Thunder may not even delve into the idea but rather focus on its own standalone narrative instead.
