The new trailer for Thor: Ragnarok released at Comic-Con International was packed with crowd-pleasing moments, from gun-toting gods of thunder and mischief to the reveals of Fenris Wolf and Surtur. But one of the biggest moments is reserved for the end, where Thor and the Incredible Hulk hold an actual conversation.

That's right, no more "Hulk smash!" but instead, "Yeah, same. Hulk like fire, Thor like water." OK, it's not exactly Shakespeare, but the point is, Hulk is talking in sentences, even if it's like "a 2-year-old." But why, and why now?

"I was always fascinated by the duality of Hulk and Banner, and seeing how their brains could be interconnected," director Taika Waititi told IGN at Comic-Con International. "Could we sometimes see Hulk and could we have a bit of Banner's voice in there? Could we see Banner and have Hulk's personality through there? And I think in this film we're going to see that for the first time, where the two are fighting -- really fighting this time -- for control of the body.  And Hulk talking, this idea of a more cognitive Hulk who can say sentences -- that obviously has existed in the comics, but I think it's something the fans want to finally see. [...] It's exactly what fans want to see, and what I wanted to see too."
