Pulling from two beloved science fiction series, Jessi from Kyle XY, and the Lord Marshal from Chronicles of Riddick have both been cast in Marvel's new superhero movie Thor.

According to the Hollywood Reporter:

[Jaime] 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 — the studio isn't even sending the actors the script — though it is known to be a villain.

Here's a picture of Sif who was the friend of the young Thor, and grew into a great warrior/crush. The film will begin shooting in October and will focus on Thor's mighty fall to Earth, where he learns the real meaning of heroism.
