Venkman Here with a geeked out discussion. This is only my opinion, but I think it is a good one that makes allot of sense. I was talking to my brother about 'The Incredible Hulk' movie and he mentioned something that I just didn't think about while watching the movie, but now it makes total sense! You may remember this scene.
After the battle with Blonsky at the Campus Hulk and Betty end up in North Carolina's Great Smoky Mountains National Park, Betty wakes up in a cave during a massive thunder and lightning storm that came out of no where. The Hulk is staring down at Betty curiously and she screams. Hulk jumps and hits his head on the ceiling of the cave, she then starts to calm him down. Suddenly, lightning strikes and Hulk starts screaming at it, every time lightning struck Hulk would just get pissed off and yell at it at the top of his lungs he got so aggravated that he eventually threw a rock into the sky at the lightning.
I remember watching that scene and wondering why Hulk was getting so pissed off. The scene also lasted a good amount of time. Enough time to make a point. The point being that the lighting was caused by Thor and Hulks behavior is his recognition of Thor. There is a 5 year span that we don't really know about before the the movie began, and there could have been a Thor and Hulk confrontation during that time. We don't know but it would make sense. Hulk and Thor do have a history.
From what I understand from some research there is a point in the Marvel Universe where...
...Loki uses the Hulk as a lure to draw Thor out; while this proved successful, it results in the formation of the superhero team the Avengers, of which Thor is a founding and longstanding member.
This is just an observation but, this would make perfect sense for the Hulk to be a villain in the Avengers movie like Marvel has been talking about. The Hulk Vs. Thor Animated movie that is coming out is the story of Loki using Hulk to kill Thor. Maybe this all ties in. But in the end I think the Hulk yelling at the thunder and lightning storm is a reference to Thor. As is the most obvious link to the world when Bruce is in the hospital and over the loud speaker you hear "Paging Dr. Donald Blake"
What do you all think?
