"Jaimie Alexander ('Kyle XY') and Colm Feore [('24')] have joined the cast of Marvel Studios' comic book adaptation Thor, to be directed by Kenneth Branagh.
Alexander and Feore join Chris Hemsworth, already cast as Thor; Tom Hiddleston, who plays Loki, the god of mischief who serves as the movie's villain; and Natalie Portman is Thor's human love, Jane Foster.
In Marvel's epic , Alexander is playing Sif, a skilled Asgardian warrior who can hold her own against any man. She also is one of Thor's loves.
Feore's character is shrouded in mystery, though it is known to be a villain.
The Thor movie spans the Marvel Universe; from present day Earth to the realm of Asgard. At the center of the story is The Mighty Thor, a powerful but arrogant warrior whose reckless actions reignite an ancient war. Thor is cast down to Earth and forced to live among humans as punishment. Once here, Thor learns what it takes to be a true hero when the most dangerous villain of his world sends the darkest forces of Asgard to invade Earth."
I was wondering when Sif was gonna get cast.
