It's a long wait until May 4, but at least we now have a tantalizing teaser clip to obsess over; let's dissect key scenes for clues
Here we see a New York City street detonating, though we don't quite know the origin of the trouble. We don't know who is causing it, or why. Loki (Tom Hiddleston), the villain in Thor (and the title character's brother), is also the central heavy in The Avengers, and he brings an alien army to help conquer Earth as his new kingdom (after he got the boot from his own homeworld at the end of Thor.) Obviously, he's planning on doing some redecorating.
