Valkyrie makes her live-action debut in the film, portrayed by Creed star Tessa Thompson. In a departure from the comics, this version of Valkyrie is black rather than white. Though this initially attracted a small amount of controversy (similar to the casting of Idris Elba as Heimdall in the first Thor movie), critics went on to praise Thompson's performance. She ended up being nominated for both a BAFTA and Saturn Award for her portrayal.

In the film, Valkyrie is introduced as a scrapper and bounty hunter who works for the Grandmaster on the world of Sakaar. When Thor crash lands on Sakaar after having been defeated by Hela, Valkyrie captures him and turns him over to the Grandmaster for a fee. Realizing she is an Asgardian, Thor attempts to get her to help him escape and save Asgard, but she refuses. As the film progresses, it is eventually revealed that Valkyrie was once a member of an elite team of warriors who served Odin, and was left as the sole survivor of the group after they were decimated by Hela. After this, she fled Asgard, and has been in hiding on Sakaar ever since. However, she eventually relents, and decides to help Thor and his friends on their quest to free their home. At the close of the film, Valkyrie chooses to continue journeying with Thor, who has now become the king of the surviving Asgardians after the death of Odin.
