Thor: Love and Thunder - The official synopsis for the fourth Thor film is yet to be revealed, but it has been confirmed that Natalie Portman’s Jane Foster will return and even wield Mjolnir as Lady Thor. Fans will remember that in Avengers: Endgame, Thor redeemed the Mjolnir using time travel and shared it with Captain America while he wielded the Stormbreaker in their final fight against Thanos.
