Chris Hemsworth is just as excited as the rest of us about the upcoming release of Avengers: Age of Ultron. but shooting the film was a particular challenge for him as the God of Thunder.

“My wife and I were having a baby — or two babies! — at the beginning of the shoot, so we were in LA.”

As for the script for the new Avengers flick, he promises more of what we loved about the first film.

“It was awesome. I just loved how it upped it in a way that wasn’t just bigger and flashier. Everything had been amplified, but in an intelligent way. All the stories are relevant to what’s going on in the world, as far as the exponential growth of technology, and artificial intelligence, and the questions of good vs. bad, and the AI world. And you know [it’s] obviously heavily influenced by that time and that debate.”

Sometimes ensemble films bring in characters that really don’t have much to do, the audience just expects them to be there. If they were missing, there would be questions about why they were absent. Chris Hemsworth says that writer/director Joss Whedon avoided that pitfall.

“[Joss] managed to bring all of the Avengers back in and give them a relevant reason to be there and justified conflict. It’s a tricky balance. I’m glad I’m not the one writing the thing and having to pull that off. There’s a new threat in this. There’s a new conflict. There’s a new set of circumstances. They don’t tend to cover too much of the previous and the next one. This, hopefully, will stand alone as its own story.”

But what about the end of the series?

Hemsworth says that an ending for the Avengers series is planned. It’s not going to go on forever. But apparently neither he nor any of the others know what that plan is. The good news is, it will be a while before it happens.

“We don’t know how it’s going to end and the biggest concern is this one here — more so than two or three films [ahead]. I know that I’m sure they are coming up with ideas and attempting to kind of have some kind of arrangement that, five or six years down the track, they go, ‘OK, this is where we’re heading.’ But they don’t tell us until the day before usually. Like, this fight scene we learned this morning!”
