I haven't seen Thor yet (it's out today!), but I did see one of the production photos.
Whoever the villains are in this movie look pretty cool. I'm a fan of the masks and the gold and black color scheme. I'm not sure how effective these troops will be, but chances are they'll make good henchmen.
Of course, there's some pretty large shoes to fill in that territory.
When it comes to spectacularly mediocre henchmen who end up being good punching bags for the hero of the story, there's a decent group of candidates out there already.
