Well, with that scene in question... Spoiler I got the impression that Thor's proximity to the hammer creates the weather distrubances. It happens again when he is reuinted with Mjolnir Also, BT, regarding your question Spoiler Apart from singlehandedly slaying about 5 times as many Frost Giants as any other characters, with total ease, the hammer throw we see in the trailer? Actually takes out about 15 Frost Giants. That giant beast, he flies through it's open mouth and out the back of it's head. That and the Destroyer scene, no matter how fast it goes, is truly awesome. That felt like the most iconic Thor scene to me... Seeing this figure, way up in the eye of a huge storm, spinning Mjolnir around and casting a tornado. He raises up Destroyer into the eye of the storm, along with cars etc. Then, after bashing hellfire blasts back at him, he flies straight into him, deflecting the hellfire all the way back at him until he's firing it at himself then he explodes. Smoke clears and we see Thor walking calmly towards Jane, with debris and cars just falling all around him. Epic.
