The Hollywood Reporter has released the names of two actors who have been added to the cast of Disney/Marvel’s upcoming film adaptation of Thor, which is being directed by the acclaimed Kenneth Branagh and stars Chris Hemsworth (Star Trek) as the titular hero and Tom Hiddleston as Loki, Thor‘s nefarious half-brother.

The latest casting news is that actress Jaimie Alexander (Kyle XY) will be playing the role of Sif, a female warrior from the mystical realm of Asgard (land of the Norse gods), who is also one of Thor‘s love interests. The other name released was that of Colm Feore (24), who will be playing a yet-unnamed villain in the film.

If you haven’t yet heard what’s in store for the big screen adaptation of Thor, here’s a quick synopsis:

The Mighty Thor is a powerful but arrogant warrior whose reckless actions reignite an ancient war. Thor is cast down from the mystical realm of Asgard to Earth and is 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.

Alexander’s character, Sif, has been the focus of a couple of casting rumors; at one point it was being whispered that actress Jessica Biel was being eyed for the role. Just by the synopsis given above, we can extrapolate that Alexander’s Sif will be Thor’s lover at the start of the film (while The God of Thunder is still happily at home in Asgard). Once Thor is cast down to Earth, we already know his heart will wander toward human nurse Jane Foster, played by Natalie Portman. Cat-fight to ensue.

What’s really got me scratching my head, though, is the question of which “villain” Feore is playing. The man is a great character actor and can be very maniacal when he wants to be – but who do they have him playing (Malekith? Pluto? Seth)? I would totally believe Loki if that part weren’t already cast… Guess I’m just not familiar enough with the Thor mythology to figure it out.

Thor is slated to strike theaters on May 20, 2011.
