In the second, Hulk goes to Asgard and tussles with Thor. Could Loki be responsible?
I've seen the Hulk Vs. Wolverine portion and it's great. It's not your water-down Saturday morning stuff. There's violence. There's lots of 'Hulk Smashing.' Wolverine gets his claws dirty (and bloody). It's great that we're not being insulted. Craig Kyle and Chris Yost are not just great writers. They're also big fans themselves. They know these characters and want to stay true to them. When I spoke to them last summer at Comic-Con, I was amazed by the amount of psychological characterization they thought about when it came to the Hulk. Sure he smashes things a lot but there is more to him than just that.
Here's some video clips, not that you really need any more reason to want to buy this the day it comes out.
