Marvel has officially announced the cast of their upcoming film "Thor: Ragnarok," confirming Cate Blanchett as Hela and Tessa Thompson as Valkyrie. Additionally Jeff Goldblum and Karl Urban have joined the cast as Grandmaster and Skurge, respectively. The announcement also confirms that Mark Ruffalo will appear in the film as Bruce Banner/Hulk. The announcement also came with the first piece of art from "Thor: Ragnarok," depicting the silhouette of Blanchett's villain Hela.

Among the returning cast members from previous "Thor" films are Chris Hemsworth as Thor, Tom Hiddleston as Loki, Idris Elba as Heimdall and Anthony Hopkins as Odin. Asgardians like the Warriors Three (Fandral, Volstagg and Hogun) and Lady Sif, who appeared in the previous two "Thor" films, are not among the announced cast. Although when asked by a fan on Twitter about Sif's exclusion, Jaimie Alexander replied with a wink.

"The continuation of the epic 'Thor' franchise will be powerful and unique, and with the additions of Cate, Jeff, Tessa, Karl, and Mark to the cast we have the makings of his most dangerous and heroic adventure yet," said Producer Kevin Feige in the announcement. "The sheer, raw talent each of these actors brings to the screen can't be quantified. Having any one of them join the Marvel Cinematic Universe would be an honor, and having all of them is incredible."

Blanchett's Hela is the first major female villain in a Marvel Studios film; Karen Gillen previously played Nebula in "Guardians of the Galaxy," who worked under Lee Pace's Ronan. The announcement confirms rumors that Thompson would play Valkyrie. Valkyrie is another Asgardian superhero who has over the years served as a prominent member of teams like the Defenders and Secret Avengers.

The inclusion of Grandmaster, played by Goldblum, speaks to the film's previously announced cosmic leaning. In the comics, Goldbum's character is an Elder of the Universe and cosmic being with millennia worth of knowledge. Karl Urban will play Skurge, a classic axe-wielding Asgardian villain sometimes known as the Executioner.

Directed by Taika Waititi, "Thor: Ragnarok" arrives in theaters on November 3, 2017.
