Joss Whedon has not been shy about boosting the already high anticipation for the second installment of the 'Avengers' series, revealing some of most awesome spectacles we can expect to see.

In a recent interview with Yahoo UK the director speaks a bit on the "unhinged climax" of the movie and makes reference to the Comic-Con art featuring the Avengers in an epic battle with Ultron and his drones. Whedon says:

"Avengers: Age of Ultron got larger than the first film. I didn't mean for it to get larger, but the climax that I pitched was completely unhinged and nobody said no, so that's that. The biggest thing for me [in 'Avengers: Age of Ultron'] is to go deeper with the characters."

"Now that people accept the reality where Thor, Iron Man and all these guys hang out, I can now bend that reality. I've got Quicksilver and I've got Scarlet Witch and they have very different ways of looking at the world, looking at The Avengers and different powers. So that visually and emotionally, we can go to a place that we didn't have access to the first time."

On the Ultron drone battle Whedon comments:

"I knew before I made the first film that Ultron needed be in the second one, along with Scarlet Witch and Quicksilver as well. The way I approach a story is that I find these moments by thinking, 'You know what I need to see?' And generally if they work, you go from there."

"You know they're going to fight Ultron. You know Ultron has a tendency to build hundreds of Ultrons. So that's going to lead you in a certain direction, but the hard work of the thing is making sure everyone feels serviced and integrated. So, in the beginning it's fun. You're thinking, 'What would be fun, what would be cool?'"
