1:54 Hulk catching a falling Iron Man and scraping against a building
2:15 Non-CG shot of Thor and Cap looking up
2:19 Monster chasing Iron Man around corner of building
This one is the best trailer yet, in my opinion, and I couldn't be more excited to see this one when it comes out on May 4. For those interested, there is also a gallery of hi-res stills from the trailer here.
