Someone on The Avengers IMDB message board has posted a topic claiming they have a credible friend (yeah yeah same story as always) that got to see an advanced screening of a short scene from The Avengers. Though, I have to say, I wouldn't have posted this unless it seemed at least somewhat credible. The events described make sense based off what we know.
Anyways, here's the description:
It starts off on a bridge where we see the Hulk roaring at what looks like a line of Shield officers trying to hold him off from getting any further down the bridge. I'm assuming this is the same scene that was from the Russian trailer that was shown a while back, so I'm now fully convinced that the trailer description wasn't a hoax.
Anyways, we then see Fury behind the line with a megaphone saying (and I'm trying the best I can to remember the dialogue on point for the entire clip) "Mr. Banner, all I want to do is talk to you, but not like this. I've got a lot of firepower in front of me and I'd really rather not have to use it." We then see Iron Man hover down slowly behind the Hulk saying "No offense Nicky, but I think that kind of firepower is a little outdated to have any affect whatsoever on this fella." The "Nicky" line got some giggles out of the audience. The Hulk turns around and faces Iron Man, who seems to be about 100 feet or so away. We then see Thor descend down from behind Iron man, and Cap stopping at the same spot on his motorcycle. Cap gets off his motorcycle and runs to the sides of Iron man and Thor.
We then see Hulk make a grimacing face as he slightly growls, waiting for them to do something. Thor then says, "I think this foe has proven that it's going to take more than a shield and a man of iron to take him down." He then starts to walk proudly towards the Hulk. Cap then yells something like "Take it easy Thor." As Thor gets closer to Hulk, he starts to say as he stops right in front of him, "You have proven that are a true opponent indeed. But do you know how many monsters I've taken down in seconds that were ten times your size?" At this point Hulk does not look amused in the slightest. Thor continues saying something like "Now you can calm down and exchange words with us, or I'll make sure that you never--" At some point at whatever he was saying, Hulk back hands him while he was speaking mid sentence, causing Thor to drop the Mjolnir and flail all the way down into the water under the bridge. This part got a lot of laughs as well, and I'm sure that was the intention, as well as to show Hulk's strength and Thor's arrogance.
Iron Man then says something like "Well I guess the Man of Iron up next." We see Hulk trying to lift Mjolnir of the ground, but unable to do so. Iron Man then flies and charges towards Hulk, charging his repulsors. Before he can fire, Hulk gives up on the Mjolnir and grabs Stark's arm and throws him at the line of Shield officers. On the ground, his helmet starts sparking so he throws it off, and it rolls towards Hulk. Hulk picks it and starts roaring again, until he is nailed in the back of the head by Caps shield. Cap catches his shield as it returns to him, and Hulk turns around slowly while growling. We then see that shot that was released a while ago of a figure holding stark's helmet, so it's confirmed that the figure is actually the Hulk.
Anyways, Hulk starts charging towards Cap, and Ca runs towards him, leaps over him, and smacks his head with the shield mid-air. That was really cool to see. Then at one point Hulk grabs Cap and pins him the the ground with one hand. Trying to help, Sheild starts firing at his back, but it doesn't do anything in the slightest. Fury says to Stark, "You want to use some of your UPDATED weapons?" in a sarcastic but urgent manner. Stark then says something like his suit is malfuctioning. Hulk starts to raise his fist, getting ready to slam it on Cap.
Just when he is about to smash him, he hears a whistling sound, looks up, and see's Mjolnir coming directly at his face. The hammer knock the Hulk off of his feet, releasing Cap, and is falling back mid air about to land on the line of Shield officers and Fury and Stark. They all scurry to get out of the way before they get crushed by the Hulk's body. Hulk lands on his back. He looks dizzy and much calmer as a bunch of the shield guards surround him and point their guns at his face. We see Mjolnir fly back to a now soaking wet Thor, who simply says "I told you." And that was it. That's all I can remember from the one screening I saw. I'm sure I missed a lot of cool bits, but it was so fast paced that it was hard to keep track. It was possibly the coolest action sequence of any Marvel movie yet, though I have to say.
