Sif, Thor's former Asgardian love (and sometime ubergirl) has been cast! And its part-time ubergirl, Jesse Alexander, who played the female counterpart to Kyle XY in the series. Here is the poop as per SHH:
Jaimie Alexander ("Kyle XY") and Colm Feore 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.
I still think this one will bomb, but I hope I'm wrong.....
