The First Awesome Trailer For 'Thor: The Dark World'

"Iron Man" won't be the only Avenger we see return to the big screen this year.

The first trailer for "Thor: The Dark World," the sequel to the 2011 film, is here and it's great.

Here's the synopsis from Disney:

In the aftermath of Marvel’s "Thor" and "Marvel’s The Avengers," Thor fights to restore order across the cosmos...but an ancient race led by the vengeful Malekith returns to plunge the universe back into darkness. Faced with an enemy that even Odin and Asgard cannot withstand, Thor (Chris Hemsworth) must embark on his most perilous and personal journey yet, one that will reunite him with Jane Foster (Natalie Portman) and force him to sacrifice everything to save us all.

The best part of the trailer? He has to ask his brother Loki—the villain from "The Avengers"—for help to protect his home planet.

Chris Hemsworth and Natalie Portman reprise their roles along with Tom Hiddleston (Loki) and Anthony Hopkins (Odin). Kat Dennings and Zachary Levi will join the cast.

"Thor: the Dark World" is in theaters November 8.

It will premiere in the UK earlier on October 30.

Here are a few take aways from the trailer:

The bad guy resembles a "Lord of the Rings" orc.

Natalie Portman's in trouble.

Serious trouble.

Loki (Hiddleston) with long hair!

Here's Jaime Alexander who will play Sif, another potential love interest for Thor.

And, here's a new teaser poster for the film Disney released.
