13. The Hulk's Costumes

Ahead of release, Hulk's battle costume was revealed thanks to a comic con exhibition, which revealed that he'd be wearing the same armour sported during the Planet Hulk combat scenes. Or at least a very close design.

His leisure wear is also a nod back to the comics, as the casual outfit he chooses to wear - including the surfer dude beads around his neck - are the same as those he wears in Tibet during the Ultimate Hulk vs. Wolverine comic mini-series.

At one point, Bruce Banner also dresses as Tony Stark (though it appears the glasses he wears are in fact Robert Downey Jr's own, and not any worn by Stark prior to Age Of Ultron, which is the only time he could have put them on the Quinjet).
