Jaimie Alexander (KYLE XY) and Colm Feore (TV's 24) have joined the cast of Kenneth Branagh's THOR, according to THE HOLLYWOOD REPORTER. The cast for the Marvel Studios flick already contains Chris Hemsworth as Thor, Tom Hiddleston as the god of mischief Loki, and Natalie Portman as Thor's love interest, Jane Foster. Alexander is set for the role of Asgardian female warrior Sif. Feore's part is a hush-hush villain.
