The moment that every fan has wanted since the Hulkbuster suit was teased in Iron Man 3 is going to be the biggest comic book movie moment of 2015. Of the MCU so far, perhaps even. The suggestion so far is that something leads to Hulk turning on the Avengers, or at least going berserker and threatening to run amok. You could perhaps suggest that something happens to Black Widow - his unlikely friend - to trigger his meltdown, but it seems unlikely that the only strong female lead would be wiped out. Perhaps he's unhappy that his friend Thor has gone and blames Stark? Some leaks have actually suggested that Hulk will end the film trapped within a quinjet on his way to outer-space imprisonment, but that seems to close to Planet Hulk, which has basically been pooh-poohed by everyone, including Mark Ruffalo. But everyone might be looking at this slightly wrong... The real question that nobody seems to be asking is why Hulk has to be the villain of that stand-off? Iron Man will go into Captain America 3 on the opposite side of the divide to Cap, so why can't that already be in motion by the end of Age Of Ultron? It might not actually be Hulk who loses it after all (despite that shot of him kicking over a police car). Which Age Of Ultron moments are you most excited about?
