Thor and the Hulk having a major dust-up in the helicarrier - freakin YES!!! THOR AND HULK GOING AT IT HAMMER AND TONGS. Damn, I really wanted to see this in the film, and hot-diggity, it was there!
The Hulk jumping out of the helicarrier and onto a fighter jet, which he starts tearing the shit out of. Pilot ejects, but the Hulk catches him. Holy shit!
In fact, the whole sequence of the Hulk going on a major rampage in the helicarrier is just amazing.
Cap, trying to take charge of the situation by giving orders to some cops amidst some major alien mayhem. Cops aren't really interested, until Cap displays some rip-snortin badassery in kicking the shit out of a gang of Chitauri (yeah, they used the name for the Ultimates version of the Skrulls for the aliens - though they didn't shapeshift. In truth, the aliens were a little disappointing, as they were pretty much cannon fodder) which then try to jump him. Cops very eager to start taking his orders soon after.
Tony Stark's snarks: Refers to Thor as 'Shakespeare in the Park'. Suggests Banner might keep calm by smoking a lot of weed on the quiet.
Cap and Iron Man working together to repair a shattered engine of the helicarrier. Amazingly well done, real edge of your seat stuff - a good moment that shows Stark's finer qualities really coming through.
Agent Coulson's fan-love of Cap.
The way Hulk evens the score with Thor later. Basically, one hell of a sucker punch.
Loki finally meeting the Hulk. 'You can't bully me, I'm a god-" exclaims Loki, at which Hulk just picks Loki up and repeatedly smashes him against the floor. 'Puny god,' murmurs the Hulk, striding away as Loki is left in near-catatonic shock.
End credits reveal: Thanos. That is all.
