For those of you not in the know, Thor is the Norse God of Thunder. If you need more knowledge about that here's the wikipedia page
Or better yet, why don't you buy one of the Thor comics from Marvel?
Here we have Thor (Chris Hemsworth). Now thankfully the casting was sound as with a movie such as this you need to suspend a bit of disbelief to really get into it.
Chris allows you to do this as everything is explained along the way throughout the movie.
In the role of Jane Foster is Natalie Portman, who just oozes the feeling of being unlucky in love.
Perhaps she'll find a comic book nerd who'll sweep her off her feet?
Or better yet, perhaps Thor will step up to do this?
You'll need to see the movie to find out.
Odin, the all-father, is played by Anthony Hopkins.
He's portrayal is somewhat colour-by-numbers. He does a good job of it.
He was also critical of the director (Kenneth Branagh) and of Chris throughout the production.
Don't let this distract you from enjoying Hopkins' performance, as it is sound.
And if Natalie Portman hotting up the place wasn't enough, there's also Lady Sif (Jaimie Alexander).
And then we have Thor's half-brother, Loki (Tom Hiddleston).
I very much liked Loki's part in the movie and thought Tom was great in the role. Tom doesn't play up being the God of Mischief, which is good.
Loki's role is, somewhat complex.
It certainly makes for an interesting story.
Kat Dennings also appears in the film but I'll let you google her yourself. Or better yet, go see the movie and you can oogle her! haha.
All up this is a very good film.
The only criticism I can give, and I highly recommend you take this onboard. See the 2D screening.
I saw the 3D screening and with the amount of dark scenes in the film there was a fair amount lost in transition.
All up I give this movie 8 out of 10. It's top quality entertainment.
