According to Wednesday's Hollywood Reporter, Jaimie Alexander and Colm Feore have been added to director Kenneth Branagh's big screen Thor adaptation for Marvel Studios. The actors join Chris Hemsworth as Thor; Tom Hiddleston as Loki, and Natalie Portman as Jane Foster.
Alexander is reportedly playing Sif, "a skilled Asgardian warrior who can hold her own against any man" and as comic book fans know a rival to Jane Foster for Thor's affections. Alexander is best known as the character "Jessi XX" on 33 episodes of the TV series Kyle XY.
Feore's character is apparently shrouded in mystery -- the studio isn't even sending the actors the script -- though it is known to be a villain. Feore has appeared on 24 and The Listener.
The movie's story centers on Thor, "a powerful but arrogant warrior whose reckless actions re-ignite an ancient war. As punishment, Thor is cast down to Earth and forced to live among humans. Once here, he learns what it takes to be a true hero when the most dangerous villain of his world sends dark forces of Asgard to invade Earth".
