The Star Trek: First Contact star revealed at a recent Star Trek Las Vegas convention that she has signed on for a supporting role in the Alan Taylor-helmed sequel.
Krige, best known for her role as the Borg Queen in the sci-fi series, suggested that she will be unrecognisable in the film, prompting speculation that she will be donning prosthetics or heavy make-up.
Christopher Eccleston recently joined Thor: The Dark World as the villain Malekith the Accursed. Krige has been tipped to play Alflyse, the queen of the Dark Elves.
Chris Hemsworth, Natalie Portman and Tom Hiddleston will reprise their roles for the Thor sequel. Anthony Hopkins will also return to the series to revisit his role of Odin.
Thor: The Dark World is scheduled for release on November 8, 2013.
