"Kyle XY" co-star Jaimie Alexander and "24's" Colm Feore have joined the cast of Marvel's "Thor" as a warrior goddess and a villain, according to The Hollywood Reporter.

Alexander will take on the role of Sif, an Asgardian warrior who often accompanies Thor in his battle to fight evil. Feore's role has not yet been named, but considering the involvement of Sif, we're going to speculate Feore will take on the role of demon Mephisto. In the comic books, Sif once traveled to the underworld and made a deal with Mephisto to save Thor's soul.

Also on board for the movie are Chris Hemsworth as Thor, Natalie Portman as his human love Jane Foster and Tom Hiddleston as the evil god Loki. Kenneth Branagh will direct.

"Thor" has a tentative release date of May 20, 2011.
