•
Chris Hemsworth as
Thor:A founding
Avenger and the former king of
Asgard, based on the
Norse mythological deity
of the same name. Director
Taika Waititi said that Thor is going through a
midlife crisis in the film, as he is "just trying to figure out his purpose, trying to figure out exactly who he is and why he's a hero or whether he should be a hero". Thor has a large tattoo on his back that memorializes his family and friends that have previously died. Hemsworth's twin sons Sasha and Tristan portray Thor as a child. •
Christian Bale as
Gorr the God Butcher:A scarred wielder of the
Necrosword and manipulator of shadows who seeks the extinction of the gods. Waititi described Gorr as being "very formidable" and layered. Bale felt the character had a "sort of a
Nosferatu slight attitude", and took inspiration from the music video for the
Aphex Twin song "
Come to Daddy" (1997). Waititi opted to change Gorr's facial features in the film since his original look in the comics resembles
Lord Voldemort from the
Harry Potter film series. Odd Studio created Gorr's practical makeup. •
Tessa Thompson as
Valkyrie:The king of
New Asgard, based on the mythological being
Brynhildr. Thompson and producer
Kevin Feige said the character's
bisexuality would be addressed in the film. Waititi said Valkyrie had to adjust to the bureaucratic aspects of ruling, away from the battlefield, such as dealing with the infrastructure and economy of New Asgard and hosting delegates from other countries. •
Jaimie Alexander as
Sif: An Asgardian warrior and Thor's childhood friend, based on the Norse mythological deity of the
same name. •
Taika Waititi as
Korg: A
Kronan gladiator who befriended Thor. Waititi also voices the Kronan god Ninny of the Nonny. •
Russell Crowe as
Zeus:The king of the
Olympians, based on the
Greek mythological deity
of the same name. Crowe wanted to perform the role in a Greek accent, but Waititi thought it would sound "too silly", so he had Crowe do takes in both a Greek and British accent, with Waititi suggesting the British accent be similar to the one Crowe used for
Maximus Decimus Meridius in the film
Gladiator (2000). Waititi finally concluded that Crowe was correct and used the Greek accent in the final film. •
Natalie Portman as
Jane Foster / Mighty Thor:An astrophysicist and Thor's ex-girlfriend who is undergoing
cancer treatment and who gains powers to become the Mighty Thor by wielding a reconstructed
Mjolnir, the hammer previously wielded by Thor. Portman, who did not appear in the previous film
Thor: Ragnarok (2017), agreed to return after a meeting with Waititi, who said Foster's return to Thor's life after eight years would be a big adjustment for him since she has had another life without him. Waititi added that Foster showing up dressed like Thor would be a "real mindfuck" for him. In preparation for her role, Portman took the Mjolnir
prop home to practice using it for her stunts. Additionally, the
Guardians of the Galaxy are featured in the film, with
