Yahoo! Movies caught up with Joss Whedon on the set of Marvel’s AVENGERS: AGE OF ULTRON last May and the writer/director discussed everything from a budding romance to an epic finale even bigger than the Battle of New York in 2012’s THE 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.

Going bigger isn’t always better, but this is a point Joss Whedon has already made in previous interviews, so there’s nothing to worry about here. Ultron is a major threat, so it’s not difficult to imagine the natural evolution of the story building to finale that would surpass the relatively localized battle against the Chitauri that we saw in the first film.

What’s clear (and most encouraging), is that Whedon has set out to make a different movie than the one the world fell in love with 2012. That movie is still there, and we’ll still love it, but the best strategy is to give us something else to enjoy rather than more of what we already know we like. There is no need to fear a case of diminishing marginal utility, as Whedon describes his new feature as a mix of many kinds of movies.

To me, adventure film is the best way to put it. Then science fiction, action, western, war, woman’s picture, horror movie … I’m not kidding; every single one of those things is in there.
