Natalie Portman shares her own Thor: Love and Thunder poster as The Mighty Thor. Portman played Jane Foster in both 2011's Thor and 2013's Thor: The Dark World, a scientist who gets involved romantically with Chris Hemsworth's Thor Odinson, accompanying him on his adventures throughout both films. Portman did not appear in Thor: Ragnarok and it was later revealed that the two characters had split up. However, Portman reappeared as Foster in Avengers: Endgame, when Thor traveled back in time to secure the Aether from her, which was the essence of the Reality Stone.
Portman was announced to be returning to the franchise at Comic-Con 2019, where the actress held Mjolnir onstage, revealing that she would be playing The Mighty Thor in Thor: Love and Thunder.

After picking up the hammer, Foster was transformed into The Mighty Thor, where she wielded the identity for a time, before eventually becoming a Valkyrie.
